Brain Mishears Itself if You Are Schizophrenic

Scientists have finally confirmed a decades-old theory. The “voices” heard in schizophrenia aren’t coming from outside. They’re the brain mishearing its own thoughts.

Researchers at the University of New South Wales used EEG scans to track brainwave activity. They discovered that, in people with schizophrenia, the brain fails to dampen signals from its own inner speech.

Normally, when we talk silently in our heads, the auditory cortex tones down its response. It knows the “voice” is internal. But in these patients, that filter breaks. The brain treats internal dialogue as external sound.

The study, published in Schizophrenia Bulletin (Oct 2025), offers groundbreaking insight into how hallucinations form. It also reveals how early brainwave patterns might one day help diagnose and prevent psychosis before it fully develops.

A powerful reminder that sometimes, the mind’s greatest confusion is mistaking itself for the world around it.
