Examples
-
Auditory evoked potentials are valuable to help establish or confirm a diagnosis and also to clarify the site of the lesion.
Academic text (1995) -
The amplitude of 10 averaged motor-evoked potentials at 1.2 times the motor threshold was used to assess corticomotor excitability.
Academic text (2015) -
An evoked potential threshold was then obtained and compared with the behavioral threshold, and the difference between the two was calculated.
Academic text (2008) -
The effects of middle ear disorders on the latency of evoked potentials are well established.
Academic text (2005) -
As with behavioral testing, the time involved in auditory monitoring with evoked potentials is a concern with seriously ill patients.
Academic text (1993) -
The visual processing was measured using a standard rate of light flashes (1.7 per second) in administering the visual evoked potential.
Academic text (1992) -
Somatosensory-evoked potentials (SSEP) measure electrical signals running between the peripheral nerves through the spinal cord to the brain.
Academic text (2005) -
Responses were amplified through a band-pass filter from 30 Hz to 3000 Hz and averaged over 128 sweeps in the evoked potential system.
Academic text (1998) -
Auditory evoked potentials are used to assess hearing and diagnose auditory pathway disorders.
-
In clinical settings, evoked potentials help determine how well the brain processes sensory information.
Synonyms

Morphology
The term is compositional: 'evoked' means elicited by external stimulation and 'potential' refers to an electrical difference, so together they denote an electrical potential elicited by stimulation. This is a straightforward technical compound that a learner who knows both component senses can derive, and the same construction exists in many languages (e.g. Spanish 'potencial evocado'), supporting transparency.
Etymology
Evoked potential comes from brain tests where a sound or light would evoke (cause) a tiny electrical potential (voltage) in the brain that doctors measured with small sensors on the head. That's why the term means 'an electrical response' the brain makes after a sound or light.
