Definition of Neuroscience
Neuroscience, also referred to as neurobiology, is the scientific study of the nervous system, which encompasses the brain, spinal cord, and peripheral nerves. This multidisciplinary field integrates various branches of science, including physiology, anatomy, molecular biology, psychology, and more, to explore the structure, function, and disorders of the nervous system.[5.1] The nervous system plays a crucial role in coordinating bodily activities and interpreting information from the environment, thereby influencing behavior and cognitive functions.[7.1] Neuroscience is the scientific study of the nervous system, which encompasses the brain, spinal cord, and peripheral nervous system, along with its functions and disorders.[5.1] This field is inherently multidisciplinary, integrating knowledge from various domains such as physiology, anatomy, molecular biology, psychology, and computer science to explore the fundamental and emergent properties of neurons and neural circuits.[5.1] Over the years, the scope of neuroscience has expanded to include diverse methodologies for studying the nervous system at multiple scales, ranging from molecular and cellular investigations of individual neurons to advanced imaging techniques that assess sensory, motor, and cognitive tasks in the brain.[5.1] A significant area of focus within neuroscience is cognitive neuroscience, which examines how brain structures influence mental processes, utilizing neuroimaging techniques like functional magnetic resonance imaging (fMRI) to map cognitive functions to specific brain regions.[8.1] Through these approaches, researchers aim to develop a comprehensive understanding of the neural mechanisms that underlie human cognition and behavior, including processes such as attention, perception, memory, language, and decision-making.[1.1]Importance of Neuroscience
Neuroscience plays a critical role in understanding and treating neurological disorders, emphasizing the importance of neuroplasticity in rehabilitation. Neuroplasticity, the brain's ability to restructure and adapt, is essential for recovery following neurological insults such as stroke, traumatic brain injury (TBI), and neurodegenerative diseases. Research has identified various neuroplasticity-targeting methods, including cognitive training, physical activity, non-invasive brain stimulation, and pharmaceutical interventions, which are vital for enhancing recovery and regaining function in affected individuals.[13.1] The integration of artificial intelligence (AI) technologies into neurology has further transformed clinical practices. AI algorithms analyze diverse patient data, including medical history and neuroimaging results, to identify subtle markers of neurological disorders that may be overlooked by human observation. This capability not only facilitates early diagnosis but also enables the development of personalized treatment plans, thereby significantly enhancing the quality and effectiveness of care for patients with neurological conditions.[15.1] Moreover, implementation science has emerged as a vital field that assesses local barriers to the adoption of evidence-based practices in healthcare. By employing trans-disciplinary research teams, implementation science aims to enhance the uptake of research findings into routine clinical practice, ultimately improving the quality and effectiveness of health services.[14.1] This approach is crucial for ensuring that advancements in neuroscience research translate into tangible benefits for patients. Research institutions, such as the Mayo Clinic, are at the forefront of these advancements, exploring conditions like Alzheimer's disease and employing innovative tools to identify early clinical symptoms and brain changes associated with various neurological disorders. Such efforts underscore the potential for neuroscience to inform clinical practices and improve patient outcomes.[16.1] Despite the significant advancements in neuroscience, challenges remain in integrating this knowledge into clinical practice. Barriers include differences in terminology between researchers and clinicians, the need for additional training in neuroscience, and concerns regarding the validity of neuroscience observations. Addressing these obstacles is essential for maximizing the impact of neuroscience on patient care.[26.1]History
Early Theories and Discoveries
Early theories of brain function laid the groundwork for the development of neuroscience, with significant contributions from various historical figures and philosophical traditions. One of the earliest theories, the Cell Doctrine, proposed by thinkers such as Nemesius and Saint Augustine, suggested that mental functions were localized in the brain's ventricles, or "cells." Despite its inaccuracies by modern standards, this theory was pivotal in shaping early neuropsychological thought and influenced subsequent explorations of brain function.[73.1] In ancient Greece, philosophers like Plato and Socrates engaged in discussions about the nature of the mind and its relationship to the brain. Plato, in particular, emphasized the brain's role as the organ of the rational soul, contributing to the early understanding of cognitive faculties and self-consciousness.[72.1] The influential physician Galen, in the 2nd century, further advanced the notion that the brain's fluid-filled cavities were central to its function, a perspective that dominated for centuries.[71.1] The mid-1800s marked a surge of interest in brain anatomy, coinciding with efforts to map brain structure to function. This period saw the emergence of phrenology, developed by Franz Joseph Gall, which posited that different regions of the cerebral cortex were responsible for various mental faculties. Gall's ideas were further explored by Pierre Paul Broca, who demonstrated the relationship between specific brain areas and speech articulation through clinical observations of patients with lesions in the left frontal lobe.[76.1] These developments laid the foundation for cognitive neuroscience, emphasizing the importance of understanding brain circuits and their functions.[74.1] The 16th century marked a pivotal moment in the understanding of the brain, particularly through the work of Belgian anatomist Andreas Vesalius. He produced a highly detailed map of the nervous system and contested the prevailing belief that the ventricles were the primary sites of brain function.[75.1] This challenge to established notions laid the groundwork for future explorations in neuroscience. In the early 1800s, significant theories such as phrenology, developed by Franz Joseph Gall and Johann Spurzheim, and anatomical personology emerged, influencing subsequent developments in the field.[70.1] These early theories represented a shift towards a more empirical approach to studying the brain, moving away from philosophical interpretations and towards those grounded in anatomical evidence.Major Milestones in Neuroscience
The history of neuroscience is a field that studies the structure and function of the nervous system, including the brain, spinal cord, and nerves. This history dates back to ancient civilizations, where scholars from Egypt, Greece, and Rome made early observations about the brain and its functions.[43.1] Among these early contributors was Galen, a prominent Roman physician, who conducted experiments that led to the discovery of the recurrent laryngeal nerves. His work advanced the understanding of the association between the brain and voice production, which was particularly significant in a Roman culture that highly valued rhetoric.[40.1] These foundational observations and discoveries have played a crucial role in shaping our understanding of the brain and its functions over the centuries. The period from 0 A.D. to 1500 saw further advancements, including the work of Marinus, who described the tenth cranial nerve, and Rufus of Ephesus, who identified the optic chiasm.[42.1] The doctrine of ventricular localization of mental functions was developed by Nemesius around 390 A.D., while Rhazes provided descriptions of cranial and spinal nerves in his medical texts.[42.1] The invention of the microscope and the development of chemical staining techniques by Camillo Golgi in the late 19th century were pivotal in the evolution of modern neuroscience. Santiago Ramón y Cajal's observations in 1888, which suggested that neurons are discrete entities rather than a continuous network, led to the formulation of the neuron doctrine, a cornerstone of neuroscience.[44.1] This debate between Cajal's neuron doctrine and Golgi's reticular theory continued even after they jointly received the Nobel Prize in Physiology or Medicine in 1906.[44.1] The case study of H.M. (Henry Molaison) has been instrumental in enhancing our understanding of the relationship between memory and brain function. In 1955, scientists William Beecher Scoville and Brenda Milner began studying H.M., who underwent surgery that involved the removal of specific portions of his medial temporal lobes, which are crucial for auditory processing and memory. This surgical intervention partially alleviated his seizures but resulted in profound anterograde amnesia, characterized by the inability to form new memories following the brain damage.[46.1] H.M.'s unique condition, described as having "dense amnesia, intact intelligence, and precise neurosurgical lesions," made him an ideal subject for experimental research.[46.1] Milner conducted various studies over nearly five decades, including the famous "star tracing task," to investigate whether H.M.'s procedural memory was affected by the removal of the hippocampus during surgery.[46.1] H.M.'s case became a cornerstone in memory research, building upon the foundational work of pioneers like Hermann Ebbinghaus, who laid the groundwork for systematic memory studies.[47.1] The insights gained from H.M.'s case have significantly influenced the field of memory research, allowing researchers to better understand the different components of memory and their implications for therapeutic practices in psychology.[47.1] Recent advancements in neuroimaging techniques, including functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT), have significantly enhanced our understanding of brain function. These technologies enable researchers to monitor neuronal and neurochemical activities in the living human brain, allowing for the identification of abnormal changes associated with various neurological and psychiatric disorders.[50.1] Furthermore, fMRI and electroencephalography (EEG) have become essential tools in neuroscience research, providing critical insights into changes in brain activity and the underlying mechanisms of cognitive processes.[51.1] The integration of these advanced imaging techniques continues to revolutionize the field, offering valuable perspectives on the complexities of brain function and the implications for future research in neuroscience.[51.1]Recent Advancements

Research has also highlighted the role of the immune system in neurodegenerative diseases, particularly in Alzheimer's disease, where peripheral immune cells infiltrate the central nervous system, exacerbating neuroinflammation and disease progression.[92.1] A newly discovered brain circuit that regulates inflammation has further illustrated the intricate relationship between the brain and the immune system, potentially paving the way for novel treatments for immune-related diseases.[94.1]Integration of Technology in Neuroscience
Recent advancements in neuroscience have increasingly involved the integration of innovative technologies, particularly artificial intelligence (AI) and optogenetics, which have significantly enhanced research and treatment capabilities. AI technologies have proven essential in the analysis of neuroimaging data, enabling the categorization of brain images and the identification of neurological conditions such as Alzheimer's disease. These AI and deep learning techniques decode intricate activity patterns, providing valuable insights into cognitive processes and disorders, including neurodegenerative diseases.[84.1] Furthermore, the integration of AI into neurology has yielded numerous benefits, including early diagnosis, personalized treatment plans, and optimized treatment strategies for neurological disorders. AI-powered algorithms analyze diverse patient data—such as medical history, imaging results, and genetic profiles—to identify subtle markers of neurological disorders that may evade human observation.[86.1] The future of brain mapping is also expected to be shaped by innovative technologies such as multimodal imaging and AI, which will require interdisciplinary collaborations to fully realize their potential in society.[85.1] However, the adoption of AI in healthcare faces challenges, including non-standardized medical records and stringent legal and ethical requirements to preserve patient privacy. Addressing these barriers is crucial for the development of clinically validated AI applications in neuroscience.[96.1] Ethical considerations surrounding AI, including data privacy and the potential for misinterpretation of brain activity, have become increasingly important. The embedded ethics approach can help identify and address these ethical, legal, and social issues arising from the integration of AI technology into neuroscience.[98.1] In addition to AI, optogenetics has emerged as a transformative technology in neuroscience, offering unique advantages in the research and treatment of neurological disorders. This technique allows for precise control of neuron activity using light, facilitating the exploration of unknown neuron functions and the discovery of neural circuits.[107.1] Optogenetics has already demonstrated significant achievements in advancing the understanding and treatment of various neurological diseases.[108.1] As these technologies continue to evolve, they promise to enhance patient care and deepen our understanding of complex neurological conditions.In this section:
Branches Of Neuroscience
Cognitive Neuroscience
Cognitive neuroscience is a specialized branch of neuroscience that focuses on understanding how the brain creates and controls cognitive functions such as thought, language, problem-solving, and memory.[116.1] Neuroscience, also known as neural science, is the scientific study of the nervous system, which includes the brain, spinal cord, and neural networks. This field examines how these structures develop, their functions, and their impact on behavior and cognitive processes.[118.1] Neuroscience is inherently interdisciplinary, collaborating with various fields such as mathematics, linguistics, engineering, computer science, chemistry, philosophy, psychology, and medicine to explore the cellular, functional, evolutionary, computational, molecular, and medical aspects of the nervous system.[118.1] Through the application of sophisticated techniques, researchers in neuroscience investigate the molecular mechanisms and neural correlates of behavior and cognition, thereby enhancing our understanding of how the brain processes information and regulates emotions and behaviors.[118.1] Cognitive neuroscience explores the intricate relationship between memory and problem-solving, revealing how these cognitive processes interact within the brain. The prefrontal cortex is essential for working memory, problem-solving, and abstract thinking, while the parietal lobes contribute to numerical cognition and spatial reasoning.[126.1] The connections between these brain regions, particularly through the white matter, are crucial for intelligence.[126.1] Understanding these interactions is vital for comprehending the brain's role in cognitive functions, as it is responsible for processing sensory information, generating thoughts, emotions, and behaviors, and performing tasks related to memory and reasoning.[127.1] Insights into how the brain combines individual episodic memories to solve problems further illuminate the complexities of cognitive processes.[125.1] Cognitive neuroscience also emphasizes the importance of experience and development in shaping cognitive abilities. For instance, the brain's plasticity during early development allows for enhanced learning opportunities, which can be influenced by environmental factors and experiences.[121.1] This understanding has implications for educational practices, as it suggests that teaching methods should align with the cognitive developmental stages of children, as outlined by theories such as Jean Piaget's stages of cognitive development.[124.1] By integrating findings from cognitive neuroscience into educational strategies, educators can better support student learning and cognitive growth.[123.1]Clinical Neuroscience
Clinical neuroscience is a branch of neuroscience that focuses on understanding the biological basis of neurological and psychiatric disorders, as well as the development of effective treatment strategies. This field encompasses various aspects, including the neurobiological effects of trauma, the role of neuropsychological assessments, and advancements in neuroimaging techniques. Trauma significantly impacts brain function, leading to alterations in emotional and behavioral responses. The limbic system, often referred to as the "emotional brain," plays a crucial role in regulating emotions and forming memories. When trauma occurs, the amygdala, which acts as an emotional sentinel, becomes hyperactive, triggering a cascade of neurobiological responses that can affect an individual's behavior and decision-making processes.[131.1] Understanding these mechanisms is essential for developing therapeutic interventions that address the emotional and behavioral changes resulting from trauma. Neuropsychological evaluations are essential in understanding how various brain injuries, strokes, congenital issues, or diseases affect cognitive functions such as memory, mood, language, problem-solving skills, and focus.[148.1] These assessments can also aid in diagnosing new health problems, including dementia or cognitive changes resulting from treatment.[148.1] Despite advancements in imaging technology, clinical neuropsychological assessments remain crucial, as significant brain changes can occur alongside nearly normal cognitive functioning, and individuals without detectable lesions may still experience substantial cognitive and functional limitations.[149.1] While screening instruments like the Mini-Mental State Examination are commonly used to identify cognitive problems, they are often insufficient for detecting milder impairments and may necessitate referral to a neuropsychologist for a more comprehensive assessment.[150.1] It is important for healthcare professionals to understand the limitations of these screening tools and to employ standardized procedures in administering and interpreting cognitive functioning tests.[150.1] Advancements in neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), have revolutionized the understanding of brain function in relation to psychological disorders. These technologies allow researchers and clinicians to observe changes in brain activity and structure, providing valuable insights into neurodevelopmental disorders like autism spectrum disorder and attention deficit hyperactivity disorder.[154.1] By integrating neuroimaging findings with clinical assessments, healthcare professionals can enhance therapeutic approaches and tailor interventions to meet the specific needs of individuals with neurological and psychiatric conditions.Applications Of Neuroscience
Medical Treatments and Interventions

[71] The brain: Milestones of neuroscience - ScienceDirect — It was a monumental step, but a deeper understanding of the brain's anatomy and function took a long time to follow, with many early theories ignoring the solid brain tissue in favour of the brain's fluid filled cavities, or ventricles. The influential 2nd-century physician Galen was perhaps the most notable proponent of this idea.
[72] Soul, mind, brain: Greek philosophy and the birth of neuroscience — This review provides a brief history of the leading doctrines on the essence of soul and the properties of mind professed by Greek philosophers and physicians as well as the early attempts to localize brain faculties and to explain neural disorders. In Plato's Phaedo, Socrates (471–399 B.C.E.) squarely faces the issue of the origin of human thoughts and sketches out with synthetic efficacy the panorama of ideas of former philosophers about the source of men's self-consciousness and cognitive faculties. Plato (427–347 B.C.E.) supported the concept of the primacy of the brain as the organ of the rational soul. This is a survey of the contribution of Greek philosophy and medicine to the development of original concepts about the nature of soul, the faculties of mind, and the structure and function of the brain.
[73] The Cell Doctrine: A Historical View on Brain Function Theories — The Cell Doctrine: A Historical View on Brain Function Theories • Psychology Town One of the most significant early attempts to understand how the brain contributes to mental functions is the “Cell Doctrine.” This theory, which emerged centuries ago, was a cornerstone in the evolution of neuropsychological thought, despite its inaccuracies by today’s standards. The Cell Doctrine was shaped by prominent figures like Nemesius and Saint Augustine, who proposed that mental functions were localized in the brain’s ventricles, or “cells.” Although modern science has disproved many of its claims, the theory played a crucial role in the development of neuroscience and psychology. As science has advanced, we have learned much more about the brain’s complex structure and functions, but the Cell Doctrine remains an important stepping stone in the history of neuropsychology.
[74] Historical Perspectives | Cognitive Neuroscience | Higher Education ... — A surge of interest in anatomy, and the brain in particular, overtook scientists in Europe in the mid-1800s, pushing the field forward.

[76] The anatomy of the brain - learned over the centuries - PMC — The belief that the cerebral cortex was composed of functional units responsible for different psychic activities contributed to the rise of Franz Joseph Gall’s phrenology (1758–1828). While trying to study the distribution of these mental faculties present reading the narrative history of neuroanatomy, we come across the detailed task of the physician Pierre Paul Broca (1824–1880) on the cortical location of the speech articulation. Although the relationship between the current inferior frontal gyrus and the integrity of speech was reported by Broca’s predecessors, it is through his publications that brain-behavioral relationships are highlighted in the 19th century. Paul Broca, through the clinical description of two patients with lesions in the same area of the left frontal lobe, comes to the conclusion that the integrity of the third left frontal convolution seems indispensable to the exercise of the articulated language faculty. This proves that efforts by Johann Gaspar Spurzheim (1776–1832), Jean Baptiste Bouillaud (1796–1881), and Achille Louis Foville (1799–1878) for phrenology were fundamental to conceptualize motor aphasia.

[116] What are some different areas of neuroscience? - NICHD — There are many different branches of neuroscience. Each focuses on a specific topic, body system, or function: Developmental neuroscience describes how the brain forms, grows, and changes. Cognitive neuroscience is about how the brain creates and controls thought, language, problem-solving, and memory.
[118] About Neuroscience - Department of Neuroscience — Neuroscience, also known as Neural Science, is the study of how the nervous system develops, its structure, and what it does. Neuroscientists focus on the brain and its impact on behavior and cognitive functions. These days, it is an interdisciplinary science which liaises closely with other disciplines, such as mathematics, linguistics, engineering, computer science, chemistry, philosophy, psychology, and medicine. They study the cellular, functional, evolutionary, computational, molecular, cellular and medical aspects of the nervous system. Behavioral neuroscience – the study of the biological bases of behavior.
[121] Brain Development and the Role of Experience in the Early Years — Brain Development and the Role of Experience in the Early Years - PMC Brain Development and the Role of Experience in the Early Years Subsequently, we examine three topics that research in brain development has uncovered, clarified, and elaborated: how development is hierarchically structured, such that later development depends on early development; how experience in the first year of life modulates the plasticity of the brain; and how early deprivation has strong and lasting effects on the brain. This child consequently may have more experience with songs, which could affect his or her language development and the brain processes that underlie it. Much of brain research is descriptive and simply tells us how the brain contributes to the development of behavior that is typical of young children (e.g., language and face processing).
[123] Growing Brains, Nurturing Minds—Neuroscience as an Educational Tool to ... — Neuroscience can inform educators about the natural learning mechanisms of the brain to support student learning. This review takes a neuroscientific lens to explore central concepts in education (e.g., mindset, motivation, meaning-making, and attention) and suggests two methods of using neuroscience as an educational tool: teaching students about their brain (content level) and considering the neuro-mechanisms of learning in educational design (design level). Neuroscience-informed educational design (teaching the way the brain learns) can promote learning motivation, high-level information processing, and knowledge retention. Teaching students about the dynamics of the default mode and executive control network can help them understand how their brain processes information, the importance of each process (e.g., extrinsic and intrinsic), and their integration for meaningful learning.
[124] Piaget's Theory and Stages of Cognitive Development - Simply Psychology — Jean Piaget’s theory of cognitive development suggests that children move through four different stages of intellectual development which reflect the increasing sophistication of children’s thought. Age-appropriate learning: The report recommended that educational activities and content should be tailored to match children’s cognitive developmental stages as outlined by Piaget. According to Piaget’s theory, children should not be taught certain concepts until they have reached the appropriate stage of cognitive development. His contributions include a stage theory of child cognitive development, detailed observational studies of cognition in children, and a series of simple but ingenious tests to reveal different cognitive abilities. Piaget divided children’s cognitive development into four stages; each of the stages represents a new way of thinking and understanding the world.

It's like a hypervigilant security guard, constantly on the lookout for potential threats.
[148] Neuropsychological Evaluation and Treatment - UPMC — A neuropsychological evaluation shows how someone's brain is working. It reveals how an injury, stroke, congenital issue, or disease affects a person's memory, mood, language, problem-solving skills, focus, and more. It also can help diagnose a new health problem, such as dementia or cognitive changes resulting from treatment.
[149] Clinical applications of neuropsychological assessment - PMC — We anticipate that clinical neuropsychological assessment will continue to be used, even in the face of advances in imaging technology, because it is already well known that the presence of significant brain changes can be associated with nearly normal cognitive functioning, while individuals with no lesions detectable on imaging can have substantial cognitive and functional limitations. For example, studies attempting to differentiate between dementing conditions of different etiologies, such as vascular dementia as compared with AD, have found little evidence of differential diagnostic utility from neuropsychological assessment.18 In fact, a fascinating book by Zakzanis et al19 that broadly approached this topic has suggested that for many conditions there is very little differential diagnostic information contained in a neuropsychological assessment that even allows for differentiation between healthy populations and patients with a variety of neuropsychiatric conditions.
[150] Neuropsychological Assessment - StatPearls - NCBI Bookshelf — Although physicians commonly utilize screening instruments to identify cognitive problems and psychological issues in patients with various neurological etiologies, situations frequently arise when referral to a neuropsychologist is needed for a more comprehensive assessment. Screening instruments, such as the Mini-Mental State Examination, are sensitive to moderate to severe cognitive impairment but relatively insensitive to milder forms of impairment; they are also susceptible to lower educational levels. Health care professionals administering and interpreting screening measures of cognitive functioning should understand and employ the standardized administration procedures of the test, have knowledge of the development of the test, and use appropriate norms and procedures to interpret test scores.

[166] 5 Neuroscience and Mental Illness - Neuroscience and Philosophy - NCBI ... — In this chapter, we will review several examples of the insights and dilemmas that have unfolded as mental illness has been examined through the lens of neuroscience, covering diagnoses such as obsessive-compulsive disorder (OCD), schizophrenia, addiction, and severe mood disorders. In particular, we examine the National Institute of Mental Health’s (NIMH) recent challenge of the ascendancy of the Diagnostic and Statistical Manual of Mental Disorders (DSM) as a guiding framework for psychiatric research with their release of the Research Domain Criteria (RDoC) framework, aimed at understanding mental illness as dysfunction in general psychological and neural systems (Kraemer, 2015). We have described ways that neuroscience at multiple levels of analyses has complicated the understanding of mental disorders, including schizophrenia and addiction, and how this might also lead to a fundamental restructuring of how we conceptualize mental illnesses and create guidelines for diagnosis, treatment, and research.
[167] The Intersection of Neurons and Mental Health: A New Frontier — The Intersection of Neurons and Mental Health: A New Frontier - Very Big Brain At their core, neurons communicate via synapses, where neurotransmitters like serotonin, dopamine, and GABA (gamma-aminobutyric acid) play a critical role in influencing mood and mental states. When neuronal activity is disrupted — by genetic mutations, environmental stressors, or neurochemical imbalances — it can lead to mental health conditions like depression, anxiety, and schizophrenia. Functional MRI (fMRI) and positron emission tomography (PET) scans are providing real-time insights into brain activity, helping researchers map the neural circuits involved in mental health disorders. Technologies like deep brain stimulation (DBS), TMS, and vagus nerve stimulation (VNS) are offering new avenues for treating depression, OCD, and other mental health conditions by directly modulating neural activity.
[169] Rapid and novel treatments in psychiatry: the future is now — These illnesses often have their origins in childhood and adolescence, and account for over a third of disabilities across the human lifespan. The devastation wreaked by psychiatric illnesses strongly underlies the need for novel, rapid, and more effective treatments. Optimistically, many in the field now believe that psychiatry is in the early phases of a revolution in therapeutics—a revolution that includes novel approaches to treatment that, in some cases, can act very rapidly (within hours to days) to produce benefits that can be sustained for several weeks or more. This issue of Neuropsychopharmacology Reviews (NPPR) presents an overview of the current state of rapid and novel treatments in psychiatry, with an eye on the future of this critical area.
[170] New insights from the last decade of research in psychiatric genetics ... — A series of large‐scale genetic studies have discovered an increasing number of common and rare genetic variants robustly associated with major psychiatric disorders. In the past 50 years, twin, adoption, family and population‐based studies of increasing quality have demonstrated that all major psychiatric disorders have a substantial heritability, meaning that a considerable proportion of the variation in risk of developing mental illness is attributable to differences in genetic factors between individuals29, 44. In autism spectrum disorder, a recent study demonstrated an inverse correlation of the burden of rare and common genetic variants among cases, indicating a spectrum of genetic risk among cases, ranging between more monogenic to polygenic risk architectures 125 . Similarly, a history of manic symptoms in schizophrenia has been significantly associated with bipolar disorder PRS218, 219, indicating that genetic risk for mental illness influences clinical subphenotypes across diagnostic categories.
