[Effect of an enriched environment on the functional and biochemical indices of the cerebral cortex of growing rats].
Experiment was aimed at studying the influence of conditions in which developing rats are kept, on conditioned behaviour, and functional and biochemical activities of the cerebral cortex. It was shown that a two-month stay of the animals (beginning with the 15th day of their life) in enriched play surroundings accelerates differential conditioning and causes an enhancement of the limit and index of photic driving on EEG, as well as biochemical shifts (enhanced activity of lactate dehydrogenase and of its isoenzymes, an increase of the content of sulfhydryl groups) in the cerebral cortex.
