[Situational conditioned reflexes in intact and callosotomized dogs when the location of conditioned and unconditioned stimuli is changed].

Positive and inhibitory conditioned reflexes were elaborated to signals, presented at the same display. Discrimination between spatially joined signals turned out to be a difficult task for intact and, in particular, for callosectomized dogs, who showed disturbances of the higher nervous activity. The analysis of spatially joined signals is possible for animals, previously trained in experiments with spatial separation of signals. With changed position of conditioned and unconditioned stimuli the callosectomized animals develop an inertness of nervous processes, manifested in a prolonged afteraction of the previously formed activity in an increased number of inadequate reactions, and impairment of differentiations.
