NPY-positive cell counts in the BNST, BLA, and CeA. a) No differences in NPY-positive cell counts between groups were seen in any of the regions examined: BNST, BLA, or CeA. b) Representative photomicrograph (40X) of NPY immunoreactivity in the CeA. Scale bar = 100 microns. c–d) Plots showing positive correlations between NPY-positive cell counts in the BNST and (c) time spent in the light arena (R2 = 0.2960) and (d) number of light-dark transitions (R2 = 0.2607).
