| Abstract | SummaryPrevious investigations on cats (4) demonstrated the importance of the motor cortex as an apparatus of convergence of visual and auditory afferent systems and of their conditioned-reflex integration. The unbreakable link between integrative activity of the brain and mechanisms of polysensory convergence was mentioned many years ago by Sherrington (22) and Ukhtomskii (21), and this problem has received more detailed analysis recently from the comparative physiological aspect (1, 10, 11, 13). Beritov (7) considers that the formation of a conditioned reflex to a combination must take place in brain structures which are excited by the combined action of all components of the combination. The frontal region in dogs, in contrast to cats, is an apparatus of polysensory convergence-a collector of afferent impulses, and it is natural to suppose that it must be responsible for certain functions in the integrative activity of the intact brain. It can be concluded from the results of the present experiments that a conditioned reflex to a simultaneous polysensory combination (flash+click) with differentiation of its components is severely disturbed after bilateral lobectomy, and to a lesser degree after destruction of the motor cortex. While disturbing inter-analyzer integration, frontal lobectomy does not give rise to appreciable motor disturbances, as occurred after extirpation of the sigmoid gyri.Probably in dogs, because of progressive phylogenetic development of the frontal lobes, as an inseparable part of the motor analyzer, these lobes have become an important component of the system of brain structures responsible for integration of polysensory information. |
