Connectivity in the developing hippocampus displays a functional organization particularly effective in supporting network synchronization, as it includes superconnected hub neurons. We have previously shown that hub network function is supported by a subpopulation of GABA neurons. However it is unclear whether hub cells are only transiently present or later develop into distinctive subclasses of interneurons. These questions are difficult to assess given the heterogeneity of the GABA neurons and the poor early expression of markers. To circumvent this conundrum we used “genetic fate mapping” that allows for the selective labelling of GABA neurons based on their place and time of origin. We show that early generated GABA cells form a subpopulation of hub neurons, characterized by an exceptionally widespread axonal arborisation and the ability to single-handedly impact network dynamics when stimulated. Pioneer hub neurons remain into adulthood where they acquire the classical markers of long-range projecting GABA neurons.
