New Study Unveils Brain Signal Disruptions Behind Schizophrenia Voices

Researchers identify faulty brain processes that contribute to auditory hallucinations, offering potential new treatment targets.

Auditory hallucinations in schizophrenia are linked to a failure in suppressing self-generated sounds and an overactive response to internal noises.
Key brain processes involved include a 'broken' corollary discharge and a 'noisy' efference copy, leading to confusion between internal and external voices.
The study used EEG to compare brain activity in schizophrenia patients with and without auditory hallucinations, revealing distinct neural disruptions.
These findings suggest that effective treatments could focus on correcting motor-to-auditory system connections rather than just the auditory system.
Researchers propose non-pharmacological interventions, such as transcranial magnetic stimulation, as potential future treatments for resistant cases.
