Efficacy and Safety of tACS vs tDCS in Schizophrenia

It is a non-invasive brain stimulation technique that uses small, pulsed alternating current (1mA) to modulate lasting cortical excitability, producing facilitatory or inhibitory effects upon a variety of behaviours, with proven efficacy in various neuropsychiatric disorders.

It is a non-invasive brain stimulation technique that uses constant, low direct current to modulate lasting cortical excitability, producing facilitatory or inhibitory effects upon a variety of behaviours, with proven efficacy in various neuropsychiatric disorders.

1mA current will be applied for the first 30 seconds to provide the initial sensation of real stimulation, and then the current will be stopped, thus minimizing the stimulatory effects. It is known to have no effect on psychopathology/neuro-cognition and means to mimic the tDCS/tACS (in order to help blinding of the participants).
