The participation of forelimb flexors in labyrinth and neck reflexes in the decerebrate cat.
The reflex behaviour of triceps and biceps brachii was assessed by EMG recordings during natural labyrinth or neck stimulation. Labyrinth reflexes resulting from changes in head position are antagonistic to those resulting from changes in neck position. Reflexes recorded from biceps were reciprocal to those recorded in ipsilateral triceps and symmetrical to those from contralateral triceps. A scheme of labyrinth and neck reflexes involving forelimb flexors is presented.
