Fos expression in the PVN. Significantly more Fos expression was shown in the PVN in LiCl and Ex-4 treated brains. LiCl activates more even Fos expression in the medial parvicellular (mp) and lateral magnocellular (lm) subdivisions of the PVN while Ex-4 has most activation of Fos in the mp subdivision of the PVN. 3V: the 3rd ventricle
