Classification of brain-stem auditory evoked potentials by syntactic methods
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1986A syntactic pattern recognition procedure for classification of brain-stem auditory evoked potential (BSAEP) is presented. A pre-processing stage of zero-phase bandpass filtering enhances the peaks and suppresses the noise. A finite-state grammar was designed to identify the peaks.

Brain stem auditory evoked potentials: The use of noise estimate
Electroencephalography and Clinical Neurophysiology, 1980One of the main difficulties with the interpretation of evoked potential data is the question of how much noise is contained within the average. This question is crucial in deciding whether any particular peak component is a genuine signal, or whether it is a random occurrence due to noise.

Brain-stem auditory evoked potentials in different age groups
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1985Brain-stem auditory potential (BAEP) latencies were measured from individuals with normal or nearly normal hearing. Different age groups were studied separately. Males have 0.1-0.2 msec longer latencies of waves III and V and longer I-V IPLs than females in all age groups.

Brain stem auditory, visual and somatosensory evoked potentials in leukodystrophies
Electroencephalography and Clinical Neurophysiology, 1982Brain stem auditory (BAERs), visual (VEPs) and somatosensory evoked responses (SEPs) were recorded in 12 patients with Pelizaeus-Merzbacher leukodystrophy (PMD), three with adrenoleukodystrophy (ALD) and three with metachromatic leukodystrophy (MLD). All the 3 evoked responses were abnormal in all patients except normal VEPs and SEPs in a patient with ...

Wave form analysis of the brain stem auditory evoked potential
Electroencephalography and Clinical Neurophysiology, 1981The BSEPs elicited by monaural and binaural click stimuli were studied using a variety of monopolar and bipolar montages. The wave form of the evoked response was different on separate montages. Evidence is presented that there are multiple generators responsible for the evoked potential recorded.

Brain stem auditory evoked potentials in unmedicated schizophrenic patients
Biological Psychiatry, 1985Numerous differences in auditory evoked potentials (AEPs) have been found between schizophrenic patients and normal controls. Roemer et al. (1979) have reported decreased stability in the AEP to click stimuli from 15 to 450 msec poststimulus: Shagass et al.

Auditory brain-stem evoked potentials in patients undergoing dialysis
Electroencephalography and Clinical Neurophysiology, 1986Auditory brain-stem evoked potentials (ABEPs) and pure-tone audiograms were obtained for 38 patients with renal failure, undergoing dialysis, before and after a dialysis session, and for 40 healthy normal subjects. Blood chemistry was also evaluated for each patient before and after dialysis.

Brain Stem Auditory Evoked Potentials in Jaundiced Gunn Rats
Annals of Otology, Rhinology & Laryngology, 1989Bilirubin 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 use

[Auditory evoked potentials of the brain stem in brain death].
Annales francaises d'anesthesie et de reanimation, 1988Brainstem auditory evoked responses were recorded in a neurosurgical intensive care unit in 38 patients who had all the clinical criteria for brain death. Of the brain-dead patients, 65.8% never showed a response. 3.42% showed a type I wave, which was unilateral in 26.3% and bilateral in the other 7.9%. Types II to VII waves were never seen.

Brain stem auditory‐evoked potentials in different strains of rodents
Acta Physiologica Scandinavica, 1990This study was conducted to evaluate variations in brain stem auditory‐evoked potentials (BAEPs) among different strains of rodents. BAEPs were recorded by routine procedures from rodents of different strains or species. These included 22 Long‐Evans, 28 Wistar and 28 Sprague‐Dawley rats, and six hamsters.
