Neurodevelopment Overview

Principles

Definition

Neurodevelopment is the complex biological process by which the nervous system forms and matures over time, encompassing the cellular and molecular mechanisms that govern the formation, organization, and function of neural circuits. As a research field and academic concept, it investigates the sequential stages from initial neural induction through cellular proliferation, migration, differentiation, axon guidance, synapse formation, pruning, and myelination, spanning prenatal life into postnatal periods. Its significance lies in elucidating the biological basis of cognitive and behavioral capacities, identifying the origins of neurodevelopmental disorders, and informing therapeutic and preventative strategies.

Key Figures

Region-Specific Maturation era

Patricia S. Goldman‐Rakic[1] was a leading figure in region-specific neurodevelopment during this era, with affiliations at Yale University[3] and the University of Chicago[4]. Her key contributions include Concurrent Overproduction of Synapses in Diverse Regions of the Primate Cerebral Cortex[7], and Development of Cortical Circuitry and Cognitive Function[8], which advanced understanding of regional maturation and cortical organization in this era. Corey S. Goodman[2] emerges as a central figure in this era, with affiliations at Stanford University[5] and the University of California, San Diego[6]. His contributions include From grasshopper to Drosophila: a common plan for neuronal development[9], Cell Recognition During Neuronal Development[10], and Embryonic development of identified neurones: differentiation from neuroblast to neurone[11], which collectively framed conserved developmental programs, cellular recognition mechanisms, and lineage progression that informed region-specific maturation.

Postnatal and Adult Neurogenesis era

Fred H. Gage [1], associated with the University of California, San Francisco [3] and Stanford University [4], stands as a central figure in postnatal and adult neurogenesis during this era. His key contributions include demonstrating neurogenesis in the adult hippocampus, as reported in 'Neurogenesis in the adult human hippocampus' [6], and establishing that 'Functional neurogenesis in the adult hippocampus' [7] can integrate into circuits and influence learning, marking a turning point for this era. Arturo Álvarez-Buylla [2], affiliated with Rockefeller University [5] and the University of California, San Francisco [3] during this era, has driven pivotal advances in postnatal neurogenesis. Her work on neurogenesis in the adult subventricular zone [8], the influence of EGF on transit-amplifying neurogenic precursors turning into multipotent stem cells [9], and in utero fate mapping of migratory pathways and fates of neurons born in the mammalian basal forebrain [10] collectively advanced models of lineage progression, migration, and integration that underpin plasticity and repair in the adult brain.

Organoid-driven Cortical Ontogeny era

Arnold R. Kriegstein [1] has anchored research in the Organoid-driven Cortical Ontogeny era through affiliations with University of California, San Francisco [3] and Stanford University [4]. His key contributions include spatiotemporal gene expression trajectories revealing developmental hierarchies of the human cortex [7], the 2018 human hippocampal neurogenesis paper [6], and the extended timeline for maturation of hPSC-derived forebrain interneurons [8], all of which were essential for aligning organoid models with human neural development. Arturo Álvarez-Buylla [2] has shaped this era through affiliations with Rockefeller University [5] and University of California, San Francisco [3]. Her contributions encompass corridors of migrating neurons in the human brain [9], the 2018 hippocampal neurogenesis study [6], and the 2013 functional maturation of hPSC-derived forebrain interneurons [8], collectively advancing our understanding of neuronal migration and development that underpin organoid platforms.
