How to Perform Transcranial DC Stimulation (tDCS) at Home?

Transcranial direct current stimulation (tDCS) is a neurostimulation technique which uses constant, low current (less than 2 mA) delivered directly to the brain via electrodes.

Currently, tDCS is used as therapy for certain psychological disorders, these days it is one of the hot topic among the bioethicists debating on using it to enhance learning in children.

Technology Review article shared an interesting post to test tDCS at home.

The idea is pretty simple, shoving 20-minute application of electrical current to your brain. The long-term effects of tDCS seems to be unknown, and if you screw up (excess current?) can obviously lead to severe brain damage or even death.

GoFlow is a startup planning to offer tDCS kits (open source) for $99. The cheapest tDCS machine costs ~$600, and you need to have a prescription for ordering too.

But, GoFlow claims that their product can help speed up learning — an effect that’s already been demonstrated by the Air Force and in the lab.

On a serious note, after seeing their promotional video, I am skeptical about the feasibly of the innovation. Its like as if I have been trolled?
