Brain-Stem Auditory-Evoked Potentials in Spasmodic Torticollis
Archives of Neurology, 1988The pathophysiology of idiopathic spasmodic torticollis is uncertain. Cerebral, basal ganglia, brain-stem, and cervicomedullary lesions have been implicated. Some investigators have found evoked-potential abnormalities, while others have not. We recorded brain-stem auditory-evoked potentials in six patients with otherwise normal result of examinations ...

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.

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 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.

Intersubject Variability of the Auditory-Evoked Brain Stem Potentials
International Journal of Audiology, 1979The potential usefulness of the auditory-evoked brain stem potentials in audiological assessment has been the subject of increased clinical enquiry. Several requirements need to be met by any response parameter if it is to be clinically useful: parameters should show a clear, and ideally simple, relationship with stimulus intensity; they should be ...

Abnormal Brain-Stem Auditory Evoked Potentials Following Ondine's Curse
Archives of Neurology, 1984Ondine's curse, the failure of automatic control of ventilation during sleep,1has been reported following lesions of the brain stem and cervicomedullary junction.1-3Although the brain-stem auditory evoked potentials (BAEPs) of two patients who were afflicted with Ondine's curse were evaluated, repeated recordings were not obtained after this central ...

Source derivation of the brain-stem auditory evoked potential
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1985This 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

Brain stem auditory evoked potentials: Reduction of evaluation errors
Electroencephalography and Clinical Neurophysiology, 1983The commonly used method of BAER evaluation is measuring the latency to the extreme points of the components. Because of the influence of noise it is sometimes impossible to determine precisely the true top of the peak. It is possible to avoid this defect by estimating the latency to the middle of the peak front. In this research S.D.s for both methods

BRAIN STEM AUDITORY EVOKED POTENTIALS IN PATIENTS WITH CONGENITAL ATRESIA*
The Laryngoscope, 1979AbstractThe 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 RECORDED DIRECTLY FROM HUMAN BRAIN-STEM AND THALAMUS
Brain, 1981Brain-stem auditory-evoked potentials were recorded in neurosurgical patients from surface electrodes applied to the VIIIth nerve, medulla, pons, midbrain and cortex; from depth electrodes in the thalamus; and from a movable electrode in the IVth, IIIrd, and lateral ventricles.
