Abstract
Sensory stimuli to the larynx evoke a laryngeal adductor reflex mediated by the brain stem via superior and recurrent laryngeal nerve. There are some reports that abnormal laryngeal reflex results in disorders of phonation and respiration. The clinical use of Larynx-evoked Brain Stem Response (LBR) as a research tool to study polysynaptic reflex pathway is considered to have a great advantage. The purpose of this report is to review the literature concerning LBR and to speculate the clinical application of LBR. In present time, there are detailed reports of LBR about validity of response, latencies, generator sources, on cat. However, there are a few reports of adaptation for use in humans.
