Distribution of afferents to the VTA coming from the mPOA. (a) Representative injection site of Fluorogold in the VTA (bar, 500µm). (b) Graph demonstrating that the number of mPOA-VTA efferents is higher in the rostral mPOA than in the caudal mPOA. (c) Photomicrographs of coronal sections profiling the rostro-caudal concentration of efferents in the mPOA, indicated by arrows. Scale bar, 250µm; values, mean ± SEM; * p < 0.001. Abbreviations: SN = substantia nigra; IP = interpeduncular nucleus; OX = optic chiasm; 3V = Third ventricle.
