Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation method that uses electrodes placed on the scalp to modulate the activity of specific cortical structures in the brain. This technique has wide applications in neurology, psychiatry, and psychology. Research findings suggest that tDCS can influence the expression of psychological traits, such as impulsivity, by stimulating brain structures involved in impulse control, such as the prefrontal cortex (PFC). The study investigated whether tDCS can reduce impulsivity levels in healthy individuals from the general population.
