The acute administration of lithium chloride significantly inhibits both prolactin and growth hormone secretion in the rat. In terms of known neuroendocrine relationships this finding indicates that lithium administration alters both dopamine (DA) and serotonin (5-HT) activity in the hypothalamus. The data suggest that DA activity is increased (inhibiting prolactin release) and 5-HT activity is decreased (reducing growth hormone stimulation). The data are in agreement with fluorescent
