CeA neurons survive 8 weeks after sdCre expression. A–C, Representative infection sites for GFP (B) and LV–sdCre (C), immunostained for GFAP. D, GFAP immunoreactivity quantification in the region represented by a dashed rectangle in A–C. E–G, Region of dense sdCre infection immunostained for GFP (E) and GFAP (F). G, Overlay of E and F. H–M, Representative infection sites for LV–sdCre injection (H–J) and LV-GFP injection (K–M). N, Quantification of cell density (Hoechst-positive nuclei/tissue volume) in the region infected by sdCre and GFP.
