Effects of treatment with scopolamine and naloxone, singly and in combination, on amygdala kindling.
Scopolamine and naloxone were administered singly and in combination to different groups of rats undergoing electrical kindling of the amygdala. Scopolamine significantly reduced the maximal seizure stage attained during 15 drug sessions and increased the total number of afterdischarges required to kindle a generalized convulsion. Naloxone had a similar but weaker and nonsignificant effect. The results confirm that antagonism of muscarinic receptors by scopolamine retards amygdala kindling.
