Polarity stimulation effects on brainstem auditory evoked potentials.
UNLABELLED Brainstem Auditory Evoked Potentials are considered exogenous potentials, that is, the responses obtained are highly dependent upon the characteristic of the stimulus used to evoke them. AIM To investigate the influence of the click stimulus polarity in the study of Brainstem Evoked Response Audiometry (BERA) at different intensities, using insertion-canal earphones. TYPE OF STUD...
متن کاملBrainstem Auditory Evoked Potentials
Brainstem auditory evoked potentials (BAEPs) are electrical field potentials generated by stimulation of the auditory pathways. With repetitive auditory stimulation, reproducible electrical potentials can be elicited and recorded from scalp electrodes. These waves are generated by specific brain regions and occur at predictable intervals. Clinically, this neurophysiological property is useful t...
متن کاملEffects of Acute Hypothyroidism on Brainstem Auditory Evoked Potentials (BAEPs)
Thyroid hormone deficiency is associated with peripheral and central nervous system (CNS) dysfunctions (1-9). CNS manifestations include somnolence, lethargy, mental retardation, memory changes, depression, and rarely convulsions and coma (10). The CNS involvement in overt hypothyroidism has previously been shown on the basis of visual evoked potentials in adult patients (11-13) and of BAEPs an...
متن کامل[Brainstem auditory evoked potentials in diabetes mellitus].
It is well-known that diabetic patients develop peripheral and autonomic neuropathy, and recent review has also suggested the occurrence of central pathway abnormality in diabetics. In this article, we conducted the BAEP study on 61 cases of NIDDM and 11 cases of IDDM. Peak latency, interpeak latency (IPL) and peak amplitude of BAEPs were analyzed in each case. For further correlation, the moto...
متن کاملEffect of Stimulus Polarity on Speech Evoked Auditory Brainstem Response
The aim of the present study was to investigate the effect of stimulus polarity on speech evoked auditory brainstem response (ABR). In order to accomplish it, speech evoked ABR was recorded with various stimulus polarities from 17 normally hearing adults. The result of the study shows differential effect of stimulus polarity on components of speech evoked ABR. Latency of peaks for onset, sustai...
