Researchers from Shanghai Jiao Tong University have identified the specific brain mechanisms that cause auditory hallucinations.

People with schizophrenia often report hearing voices that seem to come from somewhere outside themselves.

A hyperactive efference copy — the signal that tells the body to vocalize — floods the auditory system, creating a chaotic jumble of internal sounds that the brain can’t filter out.

Nearly 4 million people live with schizophrenia in the United States alone.

The FDA has approved a new drug that could change how the disorder is treated.

The hope is that one day , those voices will finally fall silent, researchers say.

The findings appeared in the journal PLOS Biology .
