Morphological Characterization Of Two Transgenic Strategies For Genetic Access To Semilunar Granule Neurons In The Mouse Dentate Gyrus, David T. Rexford

Masters Theses

Granule cells (GCs) of the dentate gyrus (DG) have been understood as a homogeneous class of neurons exhibiting a characteristic limited firing pattern. A subtype of GC called a semilunar granule cell (SGC) has been identified exhibiting variant morphology, electrophysiology, and positioning from normal GCs. SGCs represent an emerging novel subpopulation of GCs, however, there is presently no genetic tool to access SGCs separately from normal GCs. To provide access for future in vivo studies of this population, we examined two genetic strategies for putative SGC specificity in mouse brain slices. Morphological analysis was performed for quantitative identification of putative …
