“…Furthermore, neither compound decreases hippocampal5-HTrelease, and bothWAY 100135 and WAY 100635 prevent the inhibition of 5-HT release induced by 8-OH-DPAT (40,82). Similarly,infeeding studies, WAY 100135 and WAY 100635 have no intrinsic effect on food intake but blockthehyperphagic actionof 8-OH-DPAT and other 5-HTlA receptor agonists (42)(43)(44). These data provide the first unequivocal evidence from antagonist studies that 8-OH-DPAT-induced feeding is mediated by 5-HT1, receptors.…”
