The middle latency response of the auditory evoked potential may be useful as an indicator of the hypnotic state during anaesthesia. However, it is difficult to record in some circumstances. This communication provides some suggestions and guidance for those not familiar with the technique.

Objective: The objective of this study was to explore the clinical value of brainstem auditory evoked potential (BAEP) in the diagnosis of vertebrobasilar ischemia (VBI). Methods: The subjects were divided into the 2 following groups: an observation group of 300 VBI patients and a control group of 100 normal healthy volunteers. BAEP examination was carried out in both groups, and then the resul...

The brain stem auditory-evoked potential (BAEP) is an electrophysiologic test that detects and records the electrical activity in the auditory system from cochlea to midbrain, generated after an acoustic stimulus applied to the external ear. The aim of this study is to obtain normative data for BAEP in Dalmatian dogs in order to apply this to the evaluation of deafness and other neurologic diso...

The electroencephalogram, and somatosensory and auditory evoked potentials were recorded from a patient, who, at necropsy, showed a restricted unilateral thalmic infarct involving predominantly the anterior and lateral thalamus. The electroencephalogram showed distinct monomorphic delta activity and a suppression of the alpha rhythm over the side of the lesion. Short latency somatosensory evoke...

Brainstem auditory evoked potentials (BAEPs) are electrical field potentials generated by stimulation of the auditory pathways. With repetitive auditory stimulation, reproducible electrical potentials can be elicited and recorded from scalp electrodes. These waves are generated by specific brain regions and occur at predictable intervals. Clinically, this neurophysiological property is useful t...

OBJECTIVE To determine whether heart function in childhood is affected by exposure to methylmercury (MeHg) from seafood. STUDY DESIGN Prospective study of a Faroese birth cohort (N=1022). Examinations at ages 7 and 14 years included blood pressure, heart rate variability (HRV) and its frequency components of autonomic origin, and brainstem auditory evoked potentials (BAEPs). Mercury concentra...
