Question

Quizplus · Accepted Answer

The analysis of evoked potentials is a commonly used technique to determine if a stimulus has been processed by the brain. This involves measuring electrical activity in response to a specific stimulus (e.g. a sound or visual image) and comparing it to a baseline measurement of activity. The presence or absence of a response provides information about whether or not the brain has processed the stimulus. This technique is often used in research settings to study perception and attention, as well as in clinical settings to diagnose neurological disorders.
