Bessel filtering of brain stem auditory evoked potentials

Electroencephalography and Clinical Neurophysiology, 1981
It has been shown previously that conventional high-pass filtering of the brain stem auditory evoked potential (BAEP) results in significant wave form distortion. This distortion can be drastically reduced by using digital filters with zero-phase properties, but this approach requires the use of a digital computer. The Bessel filter is an approximation

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.

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.

Brain stem auditory evoked potentials (BAEP) monitoring in brain death

Neurosurgical Review, 1989
In our intensive care unit, brain stem auditory evoked potentials (BAEP) are measured continuously in comatose patients. For this study we examined 15 patients who fulfilled the criteria of brain death (2). Loss of BAEP in these patients inevitably means loss of brain stem function and consecutive death.

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.

The I’ Potential of the Brain-Stem Auditory-Evoked Potential

Scandinavian Audiology, 1992
We have consistently recorded a positive wave which precedes wave I, and is called I', within the human brain-stem auditory-evoked potential. It is postulated that I' represents initial neural activity of the auditory nerve, which presumably has as its origin auditory nerve dendrites.

Late auditory evoked potentials can occur without brain stem potentials

Electroencephalography and Clinical Neurophysiology, 1983
The sequence of early, middle and late auditory evoked potentials is well known. However, it is unknown whether the late (60-250 msec) potentials can occur independently of the early, brain stem potentials. Therefore, in 6 subjects with markedly abnormal or absent brain stem potentials, we recorded two of the late potentials: the vertex potential and ...

Recognizability of brain stem auditory evoked potential components

Acta Neurologica Scandinavica, 2009
In examining neurological patients suspected of having a brain stem lesion with brain stem auditory evoked potentials (BAEPs), a technique giving high amplitudes and/or maximal recognizability of most of the components was preferred. An increase of interstimulus intervals and stimulus strength and a widening of the band-passes of the amplifier were ...

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).

Brain Stem Auditory Evoked Potentials in Jaundiced Gunn Rats

Annals of Otology, Rhinology & Laryngology, 1989
Bilirubin encephalopathy causes potentially preventable brain damage and hearing loss. The site of auditory dysfunction is controversial, despite pathologic studies showing damage to brain stem auditory nuclei in humans and experimental animals. We studied the effects of bilirubin toxicity on the auditory system of homozygous jaundiced Gunn rats by ...
