Effects on hypothalamic self-stimulation of drugs influencing dopaminergic neurotransmission injected into nucleus accumbens and corpus striatum of rats.

abstract：:Brain 5-hydroxytryptamine (5-HT) was depleted in rats by intraventricular injection with 5,7-dihyroxytryptamine (5,7-DHT) prior to feeding rats a liquid diet containing ethanol. After withdrawal of ethanol, withdrawal reactions were significantly less severe in 5-HT-depleted rats than control rats. Sleeping times afte...
