A "thinking cap" has been created by the researchers from Vanderbilt University that can electrically stimulates the brain to increase its ability to learn from past mistakes.
Two psychologists from Vanderbilt University in Nashville, Tennessee-Ph.D. candidate Robert Reinhart and assistant professor of psychology Geoffrey Woodman-designed a cap that administers a low-level current to the brain to simulate the spike of negative voltage in the medial-front cortex.
They hypothesized that the spike plays a role in learning, allowing the brain to learn from mistakes, CNet reported.
Reinhart said that they wanted to test the actual function of these brainwaves and wanted to reach into the brain and causally control the inner critic.
The study is published online in The Journal of Neuroscience.
