Amygdala kindling after ligation of the middle cerebral artery in the rat

Cerebral infarcts were produced in rats by ligation of the right or left middle cerebral artery. A significant increase in seizure threshold and in the number of days required to develop kindled seizures was found in rats stimulated in the amygdala contralateral to the infarct. However, no significant changes in threshold or kindling rates were found in animals kindled ipsilateral to the ligation. These results were found to be independent of whether the infarct was in the right or left cerebral cortex. These data suggest that contralateral frontoparietal cerebral infarct may have inhibitory influences on seizures originating from the amygdala.
