Quizplus · Accepted Answer

The analysis of evoked potentials, which are changes in electrical activity of the brain in response to a stimulus, is a commonly used technique to determine whether or not the brain has perceived a stimulus. This method is often used in both research and clinical settings to assess sensory function. The other options listed (recording electrical activity during surgery, PET, and MRI) are not specific to determining perception of a stimulus.
