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.
在未受限的猫中，高频刺激尾状核会引发头部和身体在对侧和同侧方向的两种旋转运动。对侧旋转（CR）由更广泛的区域引发，主要占据核头部的背内侧中央部分。与它们不同的是，同侧旋转（IR）起源于腹外侧区域，更频繁地具有紧张性成分，更明显且对左旋多巴和氯丙嗪不太敏感。CR区域的单侧损伤导致同侧姿势不对称。当这种不对称消失时，给予左旋多巴或阿扑吗啡很容易引发相同方向的旋转。破坏同侧反应起源的区域则产生相反的结果。
