The distribution of GABAergic interneurons in SEF. Left, Shows coronal sections through SEF immunohistochemically reacted for the calcium binding proteins indicated. Right, Plots the location of positive neurons identified using a semi-automatic classification routine (see Materials and Methods) with associated histograms of cell counts as a function of depth. Calretinin and calbindin neurons are densest in layer II with diminishing deeper density, while parvalbumin neurons are more uniformly distributed across layers.
