Generating inhibitory neuron diversity through morphogenic patterning: From in vivo studies to new in vitro models.

The proper functioning of the central nervous system depends on the cooperation of distinct neuronal subtypes generated during development. Here, we review new insights provided by recent research and technological advances into the mechanisms underlying the generation of the remarkable diversity of inhibitory GABAergic neurons (INs). INs are generated in the ventral telencephalon or subpallium and migrate long distances to populate multiple brain regions.
