Cannabinoid use is known to disrupt learning and memory in a number of species. cholecystokinin (CCK) release and CCK receptors have been implicated in spatial memory processes in rodents. Rat hippocampal CCK interneurons express cannabinoid 1 receptors (CB1). The CB1 agonist R(+)WIN 55,212-2 (WIN+), at 1 and 10 micromol, strongly inhibited potassium-evoked CCK release from rat hippocampal slices, while the inactive isomer S(-)WIN,55,212-3 (WIN-) had no effect. CCK release from cerebral… CONTINUE READING
