[Comparative assessment of contra- and ipsiversive reactions induced by electrical stimulation of the caudate nucleus in cats].
High-frequency stimulation of the caudate nucleus provoked 2 types of rotatory movements of the head and body in the contra- and ipsilateral direction in unrestricted cats. The contralateral rotations (CR) were provoked from a more extensive area chiefly occupying the dorso-mediocentral portions of the head of the nucleus. In difference from them, the ipsilateral rotations (IR) originated from the ventro-lateral area, possessed tonic component more frequently, were more pronounced and less sensitive to L-DOPA and chlorpromazine. Unilateral damage of the area of CR led to the ipsilateral pose asymmetry. When this asymmetry disappeared administration of L-DOPA or apomorphine readily provoked rotation in the same direction. Destruction of the areas in which the ipsilateral reactions originated gave an opposite result.
