[Interrelation of the kinematics of hindlimb movement and efferent activity in the decerebrate cat during scratching].

Statistical dependence between parameters of hindlimb scratching movements and muscle electrical activity was studied in decerebrated cat during real scratching. Power of electrical signal to scratching and aiming muscles and duration of aiming muscle activity are determining factors of movement parameters (amplitude, velocity and phase duration). Experiments with limb deafferentation had shown that statistical dependences between movement parameters and muscle electrical activity reflect the peculiarities of the scratch generator functioning. Some investigated statistical dependences change under the afferent signal influence.
