Lack of summation of dynamic and static components in the responses of cat tendon organs.
Discharges of single tendon organs of cat peroneus tertius muscle were recorded during tetanic contractions of motor units. On combined stimulation of several motor units activating the same tendon organ, the static components of responses sum, although not linearly, whereas the dynamic component of a response superimposed on a pre-existing discharge does not sum at all with this discharge.
