Study investigates ‘voices’ inside the brains of people with schizophrenia
People with schizophrenia tend to hallucinate and “hear voices” that aren’t possible for others to observe.
The serious mental health condition affects people’s ability to think, takes a toll on their emotions, and majorly alters their behavior. A new study finds out what causes auditory hallucinations or “voices” in the affected minds.
Why people with schizophrenia ‘hear voices’
Schizophrenia is a complex mental disorder. It’s widely discussed in fiction and mainstream media, but what really goes on inside the minds of people affected by it was never fully understood.
New research, however, has named the cause of the “voices” they hear- more intense than the external sounds.
The study published in PLOS Biology found that auditory hallucinations are caused by abnormalities in the brain that suppress the external sounds to make the “internal voices” appear louder.

Generally, a normal brain sends a signal known as “corollary discharge” that suppresses the sound�of people’s own voices allowing the sound of the syllable they want to speak.
But the brains of people with schizophrenia not only fail to suppress the internal voices but also enhance them to overpower the planned syllable.
The authors behind the study explained: �”People who suffer from auditory hallucinations can ‘hear’ sounds without external stimuli. A new study suggests that impaired functional connections between motor and auditory systems in the brain mediate the loss of ability to distinguish fancy from reality.”
