Tac2-Cre neurons located in additional brain regions. A transverse section of a P30 adult Tac2-Cre/ROSA26-tdTomato brain showing Tomato-positive neurons (A). Note Tomato expression within the medial habenula (B, "MH"), with processes projecting ventral laterally (B, arrowhead). Tomato expression was also detected in the medial amygdalar nucleus (C, "MEA"), and the arcuate hypothalamic nucleus (D, "ARH"). Scale bar, 50 um.
