title: Mu- and delta-opioid modulation of electrically-induced epileptic seizures in mice.
abstract: Graded seizure responses to suprathreshold cerebral electroshock in mice were modified by drugs acting at mu- and at delta-opioid receptors. Morphine exerts a proconvulsant effect at a non-mu opioid receptor and may exert a simultaneous anticonvulsant effect at a mu-opioid receptor. Delta-opioid receptor blockade increases seizure severity, suggesting a predominantly anticonvulsant nature of the delta-opioid system in the seizure model tested here.
