[The dependence of the discharge frequency of muscle spindle afferents in the cat on the direction of the change in muscle loading].
Hysteretic effects in activity of the muscle spindle endings were studied using slow reciprocating changes in the external load. It was shown that the hysteretic loops of the frequency-muscle length were always broader than those of the frequency-muscle force. A conclusion has been made than the spindle tension tracking was better than the length one with respect to the corresponding static errors.
