Definition von evoked potential im Englisch Englisch wörterbuch

An electrical potential recorded from a human or animal following presentation of a stimulus, as distinct from spontaneous potentials as detected by electroencephalograms or electromyograms

EP's are recordings of the nervous system's electrical response to the stimulation of specific sensory pathways(eg visual, auditory, general sensory) In tests of evoked potentials, a person's recorded responses are displayed on a oscilloscope and analyzed on a computer which allows comparison with normal response times Demyelination results in a slowing of response time EP's can demonstrate lesions along specific nerve pathways whether or not the lesions are producing symptoms, thus making this test useful in confirming the diagnosis of MS

The electrical response in a collection of neurons that is provoked by a stimulus The electrical response in a collection of neurons that is provoked by a stimulus

the electrical response of the central nervous system produced by an external stimulus; "he measured evoked potentials with an electroencephalogram

the electrical response of the central nervous system produced by an external stimulus; "he measured evoked potentials with an electroencephalogram"

Registration of the electrical responses of active brain cells as detected by electrodes placed on the surface of the head at various places The evoked potential, unlike the waves on an EEG, is elicited by a specific stimulus applied to the visual, auditory or other sensory receptors of the body Evoked potentials are used to diagnose a wide variety of central nervous system disorders
