[Effect of peptide geroprotectors on the navigation system learning and caspase-3 in brain structures in rats of different age].

The study of the effects of peptide geroprotectors cortexin and pinealon on the system of caspase-3 in the brain structures and training of rats of different ages was held. Regional changes in activity and the content of caspase-3 in the cerebral cortex and brainstem of young and old rats under the influence of peptides were identified. It is suggested that the functional state of caspase-3 in the brain is one of the reasons that determines the animals' ability to learn.
