Endogenous opioid peptides in brain and pituitary of rats with absence epilepsy.

abstract：:In rats anaesthetized with urethane single unit activity was extracellularly recorded in the neostriatum, and several drugs were microiontophoretically ejected. Separate administration of the sulfated octapeptide cholecystokinin (CCK-8S), serotonin (5-HT) or 8-OH-DPAT (a 5-HT(1A/7) receptor agonist) predominantly indu...
