Efficacy of tACS for Treatment of Auditory Hallucinations in Refractory Schizophrenia

Transcranial alternating current stimulation (tACS) employs a weak electric current for non-invasive brain stimulation with a sine-wave waveform, targeting brain oscillations in a frequency-specific manner. daily tACS sessions were scheduled in a 5-day sequence for four consecutive weeks, and each session lasted 20minutes. Participants were administered 2 mA alternating current delivered with gamma frequency, delivered over the temporal lobe.
