Concurrently, studies have pointed to the promising effect of non-invasive cortical stimulation techniques, such as transcranial Direct Current Stimulation (tDCS), on modulating blood pressure and the ANS. tDCS involves the application of a direct low-intensity electric current between two electrodes (cathode and anode) placed on the scalp and skull over areas of interest in the cerebral cortex.
