Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have found that transcranial direct current stimulation (tDCS) of the mediofrontal cortex for a period of minutes can change a person's ability to recognize and learn from error for a period of five hours.

The foc.us gaming headset claims to improve a gamer's abilities by stimulating specific areas of the brain with a low electric current.

A study led by medical researchers at the University of Michigan has demonstrated that electric stimulation of the brain through the skull releases a powerful, opiate-like painkiller.
