The effect of beta-endorphin on hypothalamic dopamine metabolism was examined in male rats. Intracisternal administration synthetic human (15 microgram blunted the alpha-methyltyrosine-induced decline concentration dopamine. Also, pargyline-induced accumulation beta-Endorphin either increased or failed to alter basal and metabolite, homovanillic acid. These data suggest that decreases turnover rate are consistent with thesis release from tuberoinfundibular neurons.
