Personalized TACS to Reduce Rumination in Patients with Active Suicidal Ideation

A sinusoidal ± 2mA current adjusted to the individual alpha peak frequency with in-phase stimulation at parieto-occipital brain areas and anti-phase stimulation in frontal brain areas. The stimulation will involve a 10s ramp-up, followed by an immediate 10s ramp-down (no stimulation afterwards).

Active tACS with a sinusoidal ± 2mA current adjusted to the individual alpha peak frequency with a 10s ramp-up and 10s ramp-down after stimulation. In-phase stimulation will be applied to parieto-occipital brain areas and anti-phase stimulation will be applied to frontal brain areas
