Normative Data for Frequency Specificity of Acoustic Reflex Thresholds

Frequency dependence of vestibuloocular reflex thresholds.

How the brain processes signals in the presence of noise impacts much of behavioral neuroscience. Thresholds provide one way to assay noise. While perceptual thresholds have been widely investigated, vestibuloocular reflex (VOR) thresholds have seldom been studied and VOR threshold dynamics have never, to our knowledge, been reported. Therefore, we assessed VOR thresholds as a function of frequ...

Electrophysiological study of the bulbocavernosus reflex: normative data.

In the clinical setting the bulbocavernosus reflex (BCR) is elicited by squeezing the glans penis and digitally palpating the contraction of the bulbocavernosus (BC) muscle. In neurophysiology the BCR is obtained by stimulating the dorsal nerve of the penis or clitoris and by recording the response from BC muscle and it should be performed in selected patients with suspected urinary, bowel, or ...

Normative behavioral thresholds for short tone-bursts.

Although tone-bursts have been commonly used in auditory brainstem response (ABR) evaluations for many years, national standards describing normal calibration values have not been established. This study was designed to gather normative threshold data to establish a physical reference for tone-burst stimuli that can be reproduced across clinics and laboratories. More specifically, we obtained n...

Development of 90th Percentile Norms for Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study

High levels of sound pressure: acoustic reflex thresholds and auditory complaints of workers with noise exposure.

INTRODUCTION The clinical evaluation of subjects with occupational noise exposure has been difficult due to the discrepancy between auditory complaints and auditory test results. This study aimed to evaluate the contralateral acoustic reflex thresholds of workers exposed to high levels of noise, and to compare these results to the subjects' auditory complaints. METHODS This clinical retrospec...
