Rat brain atlas images (adapted from [3]) illustrating successful injection sites. Sample rat brain image of a coronal section including the DMH (top, center) with the box indicating the general region of the DMH. Successful injection sites are plotted at −2.64 mm, −2.92 mm, −3.12 mm, −3.24 mm, and −3.36 mm posterior to bregma (bottom; data points taken from (1)). Labelled structures are as follows: dorsal region of the DMH (DMD), compact region of the DMH (DMC), ventral region of the DMH (DMV), third ventricle (3 V), mammillothalamic tract (mt), fornix (f), opt (optic tract).
