Abstract
Electroconvulsive shock (ECS) significantly decreased the behavioral manifestations of seizures elicited by amygdaloid stimulation in kindled rats. This anticonvulsant effect was significantly reduced by the opiate antagonist, naloxone, and by the development of morphine tolerance. A form of footshock stress known to cause opioid-mediated analgesia had a similar anticonvulsant effect, whereas another form causing non-opioid analgesia did not. These results suggest that the anticonvulsant effects of ECS and stress are mediated by the release of endogenous opioids.
