| Abstract: | Subcutaneous post-trial administration of the neuropeptide substance P was found to reverse the amnestic effects of both electroconvulsive shock and cycloheximide. Substance P was observed to reverse the amnestic effects of cycloheximide in both C57B1/6J and heterogeneous strain (HS) mice. Substance P was found to reverse the amnestic effects of electroconvulsive seizures in C57B1/6J animals. Peripheral injections of substance P were also found to facilitate the retention of a single-trial passive avoidance habit in animals of both genotypes, provided a weak footshock was used during training. |
