| Abstract: | Characteristics of integrative activity were studied by Kupalov's method of situational conditioned reflexes in 2 groups of dogs with complete section of the callosal body and in group of intact animals. The dogs of the first group were callosotomized before the formation of the conditioned reflex systems, the dogs of the second group--after their stabilization. The level of the reflex systems integration in the first group was considerably lower than in the second one. This testifies to a special role of the callosal body in the initial period of formation of complex conditioned systems. The callosotomized dogs developed inertia of nervous processes which was manifested in slowing down of formation and of adaptive realization of reactions during integration of various reflex systems. It was shown that the integrative activity is provided for by the interaction of cerebral hemispheres at different structural levels. |
