Up until a few weeks ago, the proverbial thinking cap only had a figurative meaning, but apparently science has finally managed to catch up. A couple of American scientists have created a real thinking cap that could help people learn and make decisions quicker.
This unique device is the brainchild of psychology professor Geoff Woodman and Ph.D. student Robert Reinhart of Vanderbilt University in Tennessee and works by sending very low electrical shocks to the brain when worn. The duo claim that the electrical stimulation of certain parts of the brain could make the wearer learn new skills and make better decisions.
Indeed, studies performed on the human brain have revealed that negative voltage spikes occur in the medial-frontal cortex of the brain, milliseconds before we make a mistake. Woodman and Reinhart figured that a part of the brain can influence learning and decision making, helping us avoid the same mistakes later.
