The Proof is in the Pudding: Does tDCS Actually Deliver DC Stimulation?

Transcranial direct current stimulation (tDCS) is an increasingly used investigational modality for a variety of disease conditions worldwide, including stroke.1 It is relatively easy-use, low-cost, and has a reasonable safety profile with currents up to 2 mA. The effect of tDCS on membrane potentials has been demonstrated in vitro2 as well as in vivo through simulation of tDCS-generated electric fields.3 Real-time monitoring of applied voltage and injected current in tDCS application is offered as an inbuilt feature of many tDCS devices and can be achieved with a simple data acquisition setup.
