Question

Quizplus · Accepted Answer

Activity in the auditory cortex is greater when listening to a playback of one's own speech compared to speaking and hearing one's speech. This is because when we speak, there is a mechanism in our brain that dampens the response of the auditory cortex to our own voice, reducing the sensory feedback. This does not occur when listening to a playback, leading to greater activity in the auditory cortex.
