Question

Quizplus · Accepted Answer

Evoked potentials are a method of recording the brain's electrical activity in response to a specific sensory stimulus, such as a sound or light, which allows researchers to determine whether or not the stimulus has been perceived by the brain. PET and MRI are imaging techniques that provide information about the brain's structure and function but do not directly measure perception. Recording electrical activity during surgery is not a common method for studying perception.
