Conclusions 1. Elaboration of positive and inhibitory conditioned reflexes with spatially united auditory signals, located on a single table, is a difficult problem for both intact and callosectomized dogs. In the latter, it is accompanied by disturbances of higher neural activity. After preliminary training in experiments having changes in the locations of conditioned and unconditioned stimuli, analysis of spatially combined signals proved to be possible in callosectomized animals and was improved significantly in intact dogs. 2. With changes in the locations of the conditioned and unconditioned stimuli, disturbances were noted in the differentiated inhibition, there was an increase in the latency period of the positive reflex, and an increase in the number of inadequate responses, in both the intact and callosectomized animals. However, in the latter such changes were more marked and endured for a long time. 3. As a result of the disturbance of the joint functioning of the cerebral hemispheres resulting from callosectomy, an inertness of neural processes develops which is manifested as a prolonged afteraction of previously developed activity, and which impedes the formation of adaptive behavior during changing conditions in the environment.
