Analog and digital filtering of the brain stem auditory evoked response.
This study compared the filtering effects on the auditory evoked potential of zero and standard phase shift digital filters (the former was a mathematical approximation of a standard Butterworth filter). Conventional filters were found to decrease the height of the evoked response in the majority of waveforms compared to zero phase shift filters. A 36-dB/octave zero phase shift high pass filter...
متن کاملIntraoperative monitoring of brain-stem auditory evoked potentials.
Brain-stem auditory evoked potentials (BAEP) were monitored during 545 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 preoperatively. Reversible alterations in BAE...
متن کاملBrain-stem auditory evoked potentials in different age groups.
Brain-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. The latencies of waves I, III and V increase 0.1-0.2 msec with increasing age, but the I-V IPL was the same in all age grou...
متن کاملAlterations in brain-stem auditory evoked potentials among drug addicts
OBJECTIVE To compare the absolute latencies, the interpeak latencies, and amplitudes of different waveforms of brainstem auditory evoked potentials (BAEP) in different drug abusers and controls, and to identify early neurological damage in persons who abuse different drugs so that proper counseling and timely intervention can be undertaken. METHODS In this cross-sectional study, BAEP`s were a...
متن کاملAge and Gender Effects On Auditory Brain Stem Response (ABR)
Objectives: Auditory Brain Stem Response (ABR) is a result of eight nerve and brain stem nuclei stimulation. Several factors may affect the latencies, interpeak latencies and amplitudes in ABR especially sex and age. In this study, age and sex influence on ABR were studied. Methods: This study was performed on 120 cases (60 males and 60 females) at Akhavan rehabilitation center of university...
