1 A single in vivo cocaine administration impairs 5-HT(1B) receptor-induced long-term depression in the nucleus accumbens. Cocaine 5-hydroxytryptamine (serotonin) receptor 1B Mus musculus
2 Our results reveal a novel 5-HT1B receptor-mediated LTD in the NAc and suggest that cocaine exposure may result in elevated phosphorylation of presynaptic proteins involved in regulating glutamate release, which counteracts the presynaptic depressant effects of 5-HT1B receptors and thereby impairs the induction of LTD by 5-HT. Cocaine 5-hydroxytryptamine (serotonin) receptor 1B Mus musculus
