Summary:

- The article discusses auditory hallucinations, which are a common symptom of schizophrenia. Auditory hallucinations involve hearing voices or other sounds that are not real.

- Researchers have found that these hallucinations are caused by abnormal brain activity in regions involved in speech processing and perception. The brain's speech production areas become active, even though there is no external stimulus.

- The article explains that understanding the neural mechanisms behind auditory hallucinations can help develop better treatments for schizophrenia, such as targeted brain stimulation therapies to reduce the intensity of the hallucinations.
