Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which of the following is produced based on an average of the brain’s responses after being presented with the same stimulus many times?

A	FMRI
B	EEG
C	ERP
D	Post-mortem

Explanation:

Detailed explanation-1: -The Event Related Potential (ERP) averaging method for electroencephalographic (EEG) data [1] is one way to gain insight into how specific cognitive processes are related to brain electrical activity.

Detailed explanation-2: -Evoked potential is different from event-related potential (ERP), although the terms are sometimes used synonymously, because ERP has higher latency, and is associated with higher cognitive processing. Evoked potentials are mainly classified by the type of stimulus: somatosensory, auditory, visual.

Detailed explanation-3: -An ERP is a technique that can be used to assess how the brain is functioning in response to stimulation of the senses (e.g. sight, sound, touch, etc.). It gives a rough idea of how the brain is performing when it comes to abilities related to attention, memory, and information processing.

Detailed explanation-4: -An event-related potential (ERP) is any stereotyped electrophysiological response to an internal or external stimulus. In simple terms it is any measured brain response that is the direct result of a thought process or perception. ERPs can be reliably measured using electroencephalography (EEG).
