The effect of isometric twitch contractions of hind limb muscles on the discharge of gamma motoneurones has been studied in decerebrated cats with thoracic spinal cord section. Contractions of flexor digitorum longus (FDL) or gastrocnemiussoleus (GS) strongly inhibited the background discharge of their homonymous gamma motoneurones. In contrast, contraction(More)
The supra-segmental control of hind limb gamma motoneurones from neck muscle receptors has been studied in decerebrated and in spinal cats. Stretch of individual dorsal neck muscles was not an adequate stimulus for evoking long spinal reflexes to gamma motoneurones of gastrocnemius-soleus (GS) muscles unless the stretch was maximal or excessive.
