Highlights d GABA limits MGE-cIN participation in synchronous network events during development d Synaptic GABA regulates the emergence of interneuronpyramidal cell assemblies d GABAergic restriction of pyramidal cell activity is required for MGE-cIN apoptosis d GABA A g2-containing GABA A receptors are essential for interneuron apoptosis Authors

Highlights d In the developing barrel cortex, GABAergic neurons form functional assemblies d Prospective parvalbumin interneurons segregate into spatially clustered assemblies d Somatostatin interneurons display broadly correlated firing d GABA assemblies are regulated by sensory inputs
