[The effect of microstimulation of the motor cortex on the myotatic muscle reflexes of the elbow joint in the nonanesthetized cat].
Influence of the motor cortex microstimulation on the myotatic reflexes of the elbow joint muscles was studied on unanesthetized cats. The reflexes were evoked by the servo-controlled changes in torque or joint angle. Biceps and triceps muscles were usually coactivated. Microstimulation of the motor cortex against a background of an increase of the EMG activity usually suppressed the reflex responses in an agonist and had almost no influence on the reactions of an antagonist.
