Baclofen and the brain stem auditory evoked potential

Experimental Neurology, 1982
Abstract Baclofen, a commonly used antispastic drug, is believed to block the release of excitatory amino-acid neurotransmitters. Auditory distortions are one side effect of this drug. Peak 1 of the brain stem auditory evoked potential of the cat was not affected by intravenously applied baclofen (2 to 3 mg/kg).

Source derivation of the brain-stem auditory evoked potential

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1985
This study described the results of applying source derivation to the brain-stem auditory evoked potential. Unilateral stimulation gives rise to current sinks, associated with waves I and III, which are located in the vicinity of the ipsilateral mastoid. Waves II and V are associated with a pair of current sinks which appear bilaterally in the vicinity

Electrically Evoked Brain Stem Auditory Potentials

Annals of Otology, Rhinology & Laryngology, 1987
University of Melbourne cochlear prostheses were driven to deliver pulse stimuli at a repetition rate of 10 Hz. Brain stem auditory evoked potentials were recorded in the customary way. The magnitude of the presumed wave V was plotted against stimulus amplitude. Also, 10-Hz square waves of current were injected through a promontory needle into totally

The human auditory brain stem as a generator of auditory evoked potentials

Hearing Research, 1987
Data on the size, location, and orientation of human brain stem auditory nuclei are discussed here from the point of view of the potential role of these structures in generation of the brain stem auditory evoked response. Due to reduction in size of several nuclei in the human brain stem, the structures most likely to be generators of far-field ...

Fentanyl Anesthesia and Human Brain-stem Auditory Evoked Potentials

Anesthesiology, 1984
The effect of incremental doses of fentanyl on brain-stem auditory evoked potentials (BAEPs) was studied in 10 patients scheduled for elective surgery. Seven sets of BAEPs were recorded in each patient starting the day before surgery, after premedication and after 10 micrograms/kg increments of fentanyl up to 50 micrograms/kg.

Localizing brain stem lesions with brain stem auditory evoked potentials

Acta Neurologica Scandinavica, 2009
Based on a survey of brain stem auditory evoked potentials (BAEPs) in animals and humans with localized brain stem lesions compared to the recognizability of BAEP components in normal materials, it was concluded that BAEP examination might localize lesions to a high or low level and diffusely within the brain stem.

Vector analysis of auditory evoked potential in the brain stem

International Journal of Bio-Medical Computing, 1982
The planar vectocardiographic method was applied to auditory evoked potential in the brain stem (BAEP). It was assumed that the derivations CZ, A1 and A2 from an Einthoven triangle. BAEP were averaged simultaneously on three channels. It was assumed that if CZ were linked to A1 = lead I, CZ to A2 = II and A1 to A2 = III, then I + III = III - II = 0 ...

BRAIN STEM AUDITORY EVOKED POTENTIALS IN PATIENTS WITH CONGENITAL ATRESIA*

The Laryngoscope, 1979
AbstractThe purpose of this paper is to illustrate the value of the brain stem auditory evoked response in the definitive assessment of newborn and older infants with congenital malformations of the auditory system. Clinical cases selected illustrate the methodology required in the evaluation, and demonstrate how the technique can facilitate immediate ...

Brain stem auditory evoked potentials in posterior circulation surgery

Neurosurgery, 1983
Abstract The objectives of this study were to evaluate the use of brain stem auditory evoked potentials (BAEPs) in 10 adult patients with vascular disorders of the posterior circulation that were treated surgically and to compare the BAEPs with the neurological findings. The vascular lesions included basilar artery stenosis in 3 patients.

Auditory Evoked Potentials in Gliomas of the Brain Stem

Archives of Neurology, 1983
To the Editor. —Brain-stem auditory evoked potentials (BAEPs) play a significant role in evaluating auditory pathways and give the clinician an objective assay of the integrity of brain-stem auditory function. The test is often used as a screening tool for patients whose clinical picture is suggestive of structural abnormalities of the posterior fossa.
