title: [Characteristics of the function of the higher portions of the central nervous system of rats subjected to acute hypoxia in the antenatal period].
abstract: A reduction of motor activity, and of the orientative reflex, its more rapid extinction in comparison with control were seen in the sexually mature rats which sustained acute hypoxia during the antenatal period. The experimental animals displayed disturbances of the conditioned reflex activity indicating a worse fixation of the temporary association, weakening of the inhibitory process and reduction of the nervous process mobility. Epileptiform convulsions occurred in presentation of "difficult" experimental tasks. There was also noted an increase in convulsioness after the administration of threshold doses of carasol.
