"Injection of a highly selective 5-HT2C receptor agonist AR231630 into the ventral tegmental area (VTA) is sufficient to inhibit the expression of amphetamine-induced and basal locomotor activity as well as food intake in rats. Blockade of the anorexic effect of peripheral AR231630 on feeding by intra-VTA 5-HT2C receptor antagonist SB24208 injections suggests the involvement of 5-HT2C receptors in these effects."xsd:string
