Dopamine neurons in the posterior hypothalamus project to the spinal cord. The tuberoinfundibular dopaminergic neurons exert inhibitory control over the release of prolactin. Hyperprolactinemia has been linked to psychological symptoms, especially anxiety and depression. The ventral tegmental area (VTA) is the origination zone for dopaminergic neurons involved in reward-seeking behavior, which has been linked to addiction and substance abuse. The VTA releases galanin in response to increased activity of the locus ceruleus neurons. Galanin may inhibit the activity of dopaminergic cell
