evoked response


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

e·voked re·sponse

an alteration in the electrical activity of a region of the nervous system through which an incoming sensory stimulus is passing; may be somatosensory (SER), brainstem auditory (BAER), or visual (VER).
See also: evoked potential.

evoked response

Evoked potential Cardiology An area under an R wave that depends on the rate of myocardial depolarization; ↓ in cumulative R-wave area mandates ↑ pacing rate Neurology Any stimulus-evoked electrical potential recorded by EEG, which varies according to intensity, modality, location, and level of consciousness; ER is detectable over the appropriate cortical receptive areas by EEG after stimulation of sense organs or peripheral nerves–eg, brainstem auditory, transcortical motor, pattern shift visual, and somatosensory ERs; ERs may be used to guide surgical removal of tumors growing around important nerves. See White noise.

e·voked re·sponse

(ER) (ē-vōkt' rĕ-spons')
Alteration in electrical activity of a region of nervous system through which an incoming sensory stimulus is passing; may be somatosensory (SER), brainstem auditory (BAER), or visual (VER).

evoked response

a technique for the detection of low amplitude electrical activity in response to stimuli for the purpose of evaluating sensory mechanisms. Called also evoked potential.

brainstem auditory evoked response (BAER)
variations in electromyographic or electroencephalographic recordings in response to sound stimuli. Used to evaluate brainstem lesions and hearing in dogs.
visual evoked response r's
electrical potentials to flash or pattern displays that are recorded over the occipital lobe region.
