Neurobiology Of Disease Overview

Principles

Definition

Neurobiology of disease is an interdisciplinary research field focused on understanding the molecular, cellular, and systems-level biological mechanisms within the nervous system that contribute to the etiology and pathophysiology of neurological and psychiatric disorders, aiming to identify therapeutic targets.

Cholinergic Circuit Foundations era

Urban Ungerstedt [1] was active at Karolinska Institutet [2] and the University of Gothenburg [3] during the Cholinergic Circuit Foundations era. His 1971 paper, Postsynaptic Supersensitivity after 6-Hydroxydopamine Induced Degeneration of the Nigrostriatal Dopamine System [4], demonstrated how postsynaptic receptors adapt after monoaminergic lesions, a finding that linked cellular lesions to clinical deficits in memory, seizure, and neuromuscular dysfunction. Urban Ungerstedt [1] contributed to a framework in which neurochemical changes could be translated into functional syndromes through receptor-level plasticity and neuromodulator mapping. Urban Ungerstedt [1] thus helped crystallize the era's view of disease as altered cholinergic signaling within defined circuits.

Circuit Dysregulation and Vulnerability era

Justin C. McArthur[1] is described with affiliations at Harvard University[3] and the University of California, San Francisco[4]. His key contribution in this era centers on updating the HIV-associated neurocognitive disorders nosology, as reflected in Updated research nosology for HIV-associated neurocognitive disorders[6], a standardizing move that clarified diagnostic criteria and facilitated mechanistic studies of circuit vulnerability. Karen Marder[2] is associated with Harvard University[3] and Johns Hopkins University[5] during this era. Her contributions include the Updated research nosology for HIV-associated neurocognitive disorders[6], which helped unify clinical criteria and highlight circuit-level vulnerability in HIV-related neurodegeneration.

Microglial Immune Modulation era

Ingrid E. Scheffer[1] is a leading figure associated with Harvard University[3] and the University of California, San Francisco[4] during this era. Her key contribution in this era is co-authoring the Revised terminology and concepts for organization of seizures and epilepsies: Report of the ILAE Commission on Classification and Terminology, 2005–2009[5], which helped standardize terminology and classification across research and clinical practice. Samuel F. Berkovic[2] is a prominent researcher linked to Harvard University[3] and the University of California, San Francisco[4] in this period. As a co-author of the same ILAE report[5], Berkovic contributed to shaping global epilepsy terminology and classification, a contribution that underpins era-wide efforts to harmonize research and clinical practice in seizures and epilepsies.
