Brain mapping advances understanding of human speech and hallucinations in schizophrenia

"Voice experiments in people with epilepsy have helped trace the circuit of electrical signals in the brain that allow its hearing center to sort out background sounds from their own voices."

"Our findings also provide specific insight into schizophrenia, offering an explanation for the source of auditory hallucinations, as resulting from disrupted corollary discharge between the brain's motor and auditory cortices," said neuroscientist Adeen Flinker, PhD, study senior investigator."
