average evoked potential

average evoked potential  

The fluctuation in amplitude of an evoked potential, averaged over a large number of separate readings to eliminate random noise (2). Also called an average evoked response (AER). See also N140, ...
contingent negative variation

contingent negative variation  

A type of event-related potential, believed to indicate attention, consisting of a large negative change in potential voltage across the cerebral cortex, especially in the frontal lobe, that develops ...
Edgar Douglas Adrian

Edgar Douglas Adrian  

1st Baron Adrian (1889–1977). Adrian was born in London and educated at Westminster School, where he became a King's Scholar at the end of his first term. Like his mentor ...
electroencephalography

electroencephalography  

n. the technique for recording the electrical activity from different parts of the brain and converting it into a tracing called an electroencephalogram (EEG). The machine that records this activity ...
event-related potential

event-related potential  

Another name for an evoked potential, especially an EEG response originating outside the primary sensory areas of the brain, initiated by cognitive activity, associated with the sequential processing ...

The study of evoked brain potentials arose as an extension of the interest in the spontaneous electrical activity of the brain, recorded in ...

laterality

laterality  

The asymmetry in functions between the two cerebral hemispheres, including handedness (1) and language functions, the left hemisphere being dominant for language in approximately 90 per cent of ...
Libet's delay

Libet's delay  

A period of approximately half a second between a person's skin being touched and the resulting conscious experience of being touched, although the brain receives the signal and responds to the ...
lie detector

lie detector  

A type of polygraph sometimes used in police interrogations to detect untrue or deceptive answers by recording involuntary stress-induced physiological responses, typically including changes in ...
N400

N400  

A single sustained negative evoked potential occurring when a person encounters an unexpected or incongruous word when reading a sentence such as He spread the warm bread with socks, in which the ...
nerve conduction velocity

nerve conduction velocity  

A neural measure of processing speed proposed in 1992 by the US psychologist Arthur R(obert) Jensen (born 1923), obtained by dividing a person's head length (distance from the eye to the primary ...
neurometrics

neurometrics  

A group of techniques involving measurements of the activity of neurons in the nervous system, including EEG, evoked potentials (EPs), and event-related potentials (ERPs). [From Greek neuron a nerve ...
P300

P300  

A large positive evoked potential that occurs approximately 300 milliseconds after the presentation of a stimulus, especially one that is unexpected, interesting, or potentially important, and that ...
P50

P50  

An evoked potential in response to a brief auditory stimulus such as a click, occurring about 50 milliseconds after the stimulus. The P50 response usually decreases if the stimulus is repeated many ...
transcortical magnetic stimulation

transcortical magnetic stimulation  

A painless and non-invasive technique for studying brain function by applying a pulsed magnetic field across the skull, first used as an aid to neurological examination, by stimulating regions of the ...
visual evoked potential

visual evoked potential  

An evoked potential elicited by a visual stimulus. See also nerve conduction velocity. VEP abbrev.
