Could a gentle brain zap quiet voices in schizophrenia?

This small, early study tested a new approach called Auditory Control Enhancement (ACE) for people with schizophrenia who hear voices (auditory hallucinations) that don't respond to medication. ACE combines a mild brain stimulation technique called tDCS with cognitive training. The study aimed to see if the method is safe, acceptable, and whether it changes brain activity in areas linked to hearing and attention. Only 12 people were enrolled, and the study was terminated early, so the results are very preliminary.
