evoked response

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.
