while the neurotoxic lesion procedure used does not differentiate noradrenergic and dopaminergic damage , the importance of intact catecholaminergic systems within the habenula for effective drl acquisition is consistent with the suggested importance of the habenula for feedback regulation of dopamine within the ventral tegmental area through ascending dopamine fibers to the habenula .
