[Conditioned motor-alimentary reflexes in cats following ablation of the body of Luys].

Alimentary conditioned motor reflexes in cats were elaborated in special chambers. Subsequently, the subthalamic nucleus was damaged, first on one and then on the other side. After its unilateral destruction, temporary disturbance in the cat behaviour was observed disappearing within 2--3 weeks. Bilateral destruction of the subthalamic nucleus led to a stable disturbance in the reaction of choice of reinforcement side in conditions of uncertainty.
