Overview

• 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.
