Dendritic protrusions have a major role in the production of glutamatergic synapses. Much less is known regarding the development of GABAergic connections. This study examined contact formation between GABAergic axons and their targets, revealing that new putative GABAergic terminals were produced through the appearance of new boutons at pre-exisiting axon/dendrite crossing points, without the participation of dendritic or axonal protrusions.
