Diagnostic role of brain-stem auditory evoked potentials in neurobrucellosis

Electroencephalography and Clinical Neurophysiology - Evoked Potentials, 1992
Evoked potential audiometry and brain-stem auditory evoked potentials were evaluated in 15 patients with systemic brucellosis in whom brucella meningitis was suspected clinically. In 8 patients cerebrospinal fluid (CSF) was abnormal with high brucella titre, and evoked potentials were abnormal in all of them. In 7 patients the CSF was normal and evoked

Brain-stem auditory evoked potentials in adults with Down's syndrome

Electroencephalography and Clinical Neurophysiology - Evoked Potentials, 1992
Brain-stem auditory evoked potentials (BAEPs) were examined in 37 adult patients with Down's syndrome and in 37 age-matched normal subjects. All absolute and interpeak latencies except for the interpeak latency IV-V were shorter in patients than in normal subjects.

Brain-stem auditory evoked potentials and brain death

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1991
BAEP records were obtained from 30 brain-dead patients. Three BAEP patterns were observed: (1) no identifiable waves (73.34%), (2) an isolated bilateral wave I (16.66%), and (3) an isolated unilateral wave I (10%). When wave I was present, it was always significantly delayed.

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.

Intraoperative monitoring of brain-stem auditory evoked potentials

Journal of Neurosurgery, 1982
✓ Brain-stem auditory evoked potentials (BAEP) were monitored during 54 neurosurgical operations in the cerebellopontine angle. The BAEP were irreversibly obliterated in five patients who required deliberate section of the auditory nerve. Technical difficulties interfered with monitoring in three cases, and three patients had deafness and absent BAEP ...

Auditory Brain-Stem Evoked Potentials in Bell's Palsy

Archives of Otolaryngology - Head and Neck Surgery, 1984
In an attempt to assess objectively the integrity of the auditory pathways in patients suffering from Bell's palsy, an audiometric evaluation was performed and auditory brain-stem evoked potentials (ABEP) were obtained from 24 patients within the first week from the onset of facial weakness.

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

Intersubject Variability of the Auditory-Evoked Brain Stem Potentials

International Journal of Audiology, 1979
The 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 ...

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
