[The effect of damage to the cerebellar nuclei on acquired motor coordination in dogs].
In the experiments was studied the role of the cerebellar nuclei (n. dentatus and n. interpositus) in the realization of a conditioned motor coordination in dogs. Destruction of the cerebellar nuclei leads to disturbances of the conditioned precision movement of a forelimb and of the conditioned coordination of movements of a head decline to a feeding cap and a forelimb flexion. All the disturbances are of a reversible character. Elaboration of a new coordination is connected with the reorganization of the initial motor coordination. During the first experiments after the destruction of the cerebellar nuclei the reorganized coordination relations return to the initial ones. The cerebellum was suggested to participate in the formation and realization of the motor coordination under study.
