Dr. Sukhi Shergill explains that Broca’s area is active during auditory hallucinations in schizophrenia.
Broca’s area is very interesting. What happens during hallucinations is that Broca’s area is working significantly and that lets us know that when you’re actually experiencing a hallucination, which is hearing speech when there’s nobody around, it seems to be coming from your own thoughts because your Broca’s area is working at that time, and its overactive.
