It’s called “transcranial direct-current stimulation (tDCS),” haven’t you heard about it? The process involves zapping your brain through subtle electrical stimulation on the outside of the head – and though research has been going on in this field for decades, the mechanisms for it’s effects on mood, memory, and more, are still mostly unknown.

Dr. Brent Williams is the director of the iTeach Center at KSU, and he landed in WIRED magazine for some of his work on tDCS. In this episode, he talks about the potential future of tCDS to enhance normal human function and potentially allow us more control over our emotional state and mental performance, as the technology progresses. It’s enough to make you want to go to Radio Shack and build one yourself.
