[Action of cortical extracts of the left and right hemispheres on the recovery of conditioned reflex activity in rats after unilateral removal of the frontal cortex].
The recovery of active avoidance conditioned reflex (AACR) was investigated after unilateral frontal cortex extirpation. Intraperitoneal injection of extracts from left or right brain cortex (1 mg/kg) of healthy rats (LE or RE) stimulated AACR recovery in animals with lobectomy on the same side. If RE was extracted 9 days after left side brain extirpation, i.e. during the period of the development of compensatory processes, its effect on AACR recovery was stronger in left-operated animals, while in right-operated animals it remained unchanged.
