The recorded corneo-mandibular reflex.
Corneo-mandibular reflexes were studied electrophysiologically in 27 patients with cerebral lesions and normal consciousness. EMG demonstrated that the reflex is absent in 40 controls and may appear with lesions which involve the precentro-bulbar tract. The reflex is considered to be a pathological exteroceptive reflex. The response fell into 4 categories of decreasing spread. In 2 controls and in 2 patients with hemiplegia clinical corneo-mandibular reflexes turned out electromyographically to be corneo-mental reflex responses.
