Vanderbilt University researchers have found that sending mild stimulation to the brain can enhance or depress learning effects.

A Vanderbilt University team of researchers, led by psychologist and PhD candidate Robert Reinhart and assistant professor of psychology Geoffrey Woodman, has conducted a study that showed it is possible to selectively enhance or depress a person's ability to learn by sending a mild electrical current to the brain.

Previous studies have shown that a spike of negative voltage originates from a certain part of the brain immediately after a person makes a mistake. Reinhart and Woodman wanted to explore the idea that this brain activity has an impact on learning because it allows the brain to learn from mistakes.
