The effects of cholecystokinin octapeptide sulfate ester (CCK-8-SE), its N-terminal tripeptide (CCK-2-4-SE) and its C-terminal tetrapeptide (CCK-5-8) were investigated on hypothalamic self-stimulation in rats. CCK-8-SE and CCK-5-8 in 400 pmole doses inhibited self-stimulation behaviour, while CCK-2-4-SE was ineffective. In 80 pmole doses the peptides showed no effect. It is suggested that CCK-5-8 itself influences self-stimulation behaviour.
