“…Mochida 25 demonstrated that there were two types of responses (a latency at 8 to 10 ms and one at 40 to 60 ms) in the thyroarytenoid muscle to vibratory stimulation of the SLN in cats. Misuhashi 26 demonstrated that receptors responsible for vibratory stimulation in the cat are distributed to the supraglottic and subglottic mucous membranes, respectively. Vibratory stimulation of the SLN in this study may excite the mechanoreceptors in the laryngeal mucosa and consequently elicit LBRs.…”

Laryngeal Evoked Brainstem Responses in Humans: A Preliminary Study

Laryngeal evoked brainstem responses (LBRs) were recorded in normal human subjects in an attempt to develop a central laryngeal function test and enhance our understanding of neurolaryngologic disorders. The results showed that the human LBR consists of five positive peaks and five negative peaks reproducible within 10 ms after a vibratory stimulation to the superior laryngeal nerve (SLN). The waveform reproducibility was verified by blocking the SLN and topically anesthetizing the hypopharyngeal cavity. The morphology and latency of peak 5 were similar to results obtained in animal LBR experiments. It was concluded that a vibratory stimulation to the SLN was a noninvasive method to elicit far-field potentials from the central laryngeal pathway. These findings encourage further effort to establish normative data and explore clinical correlations.

“…A technique for electrostimulation of the SLN has been used in evoked electromyography (EMG) studies of laryngeal functions in humans 6 • 11 and animals. 12 • 13 This technique is widely used because the SLN contains the afferent fibers and because the stimulation to the SLN, whether magnetic, electrical, or vibratory, is accessible and controllable.…”

The role of the laryngeal reflex in glottal movement has been reported, but its mechanism remains unclear. To further investigate the neurophysiological characteristics of glottal movement, we recorded the laryngeal reflexomyographic responses (LRMRs) to electrical stimulation of the superior laryngeal nerve (SLN) in rabbits. The procedure involved simultaneous recording of the LRMRs from the thyroarytenoid muscles by means of bipolar hooked wire electrodes after electrical stimulation to the SLN. The results demonstrated characteristic patterns of the responses, consisting of R1 and R2, similar to those found in humans. The R1 response was obtained with a latency of 10.7 +/- 0.78 ms. The ipsilateral R2 response was obtained with a latency of 43.76 +/- 4.67 ms in all rabbits, and the contralateral R2 response with a latency from 42.6 to 50.2 ms in 4 rabbits. It was concluded that LRMRs may serve as a potential central laryngeal function test in the investigation of glottal movement control.
