Figure 4. Effects of PPS on the expression of glutamic acid decarboxylase 65/67 (GAD6) in the amygdala of rats.

Figure 4

(A) Schematic representation of the different amygdalar nuclei analyzed (Bregma −2.56 mm, Interaural 6.44 mm), modified from the Atlas of Paxinos and Watson (2006). (B & C) Photomicrographs showing the GAD6 neuropil inmunoreactivity in the amygdala of CTRL (B) and PPS (C) rats. Scale bar: 200 µm. Optical densitometry of neuropil immunoreactivity revealed a significant decrease of GAD protein levels in the amygdala of PPS animals as compared to CTRL (D). ** p<0.01 versus CTRL, results are the mean ± SEM.
