BACKGROUND Evoked potentials are used to detect conduction disturbances in the central nervous system. This paper provides an overview of the areas in which evoked potentials are used in clinical neurophysiological diagnostics, with the emphasis on coma and demyelinating disease. METHOD The article is based on a literature search in PubMed and the authors' long experience of neurological and ...

Sensory systems function most efficiently when processing natural stimuli, such as vocalizations, and it is thought that this reflects evolutionary adaptation. Among the best-described examples of evolutionary adaptation in the auditory system are the frequent matches between spectral tuning in both the peripheral and central auditory systems of anurans (frogs and toads) and the frequency spect...

Auditory brainstem response (ABR) reflects activation of the neural generators along the ascending auditory pathway when a sound is heard. In this study, we explored the relationship between brainstem encoding of click and speech signals in normal-learning children and in those with language-based learning problems. To that end, ABR was recorded from both types of stimuli. We found that the nor...

OBJECTIVE To assess the value of brainstem auditory evoked potentials and event related evoked potential (3rd positive component of evoked related potentials with latency of 300 millisecond, in evaluating cognitive dysfunction in patients with chronic respiratory failure. METHODS Thirty-two patients with chronic obstructive pulmonary disease and respiratory failure of mild to moderate severit...

There has always been a need for objective tests that assess auditory function in infants, young children, and/or any patient whose developmental level precluded the use of behavioral audiometric techniques. Although several approaches have been tried, such as acoustic-reflex threshold, middle-latency response, and late auditory-evoked potential measurements, for the past twenty-five years, tha...
