Transcranial direct current stimulation (tDCS) has become a widely used technique for reaching into a person's brain and altering the way in which it functions. Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have just published the results of a new study in the Journal of Neuroscience
in which they found that tDCS stimulation of the mediofrontal cortex for a period of minutes can change one's ability to recognize and learn from error for a period of several hours.
What would you do if you wanted to improve your video game skills? Practice more often? Study game maps? Maybe get some tips from pro gamers? But why do any of that when you can just hook some electrodes to your scalp and run an electric current through your cranium? That's what Focus Labs is offering with the foc.us headset, which it claims will improve a gamer's abilities by stimulating specific areas of the brain with a low electric current.
Twenty to thirty percent of the world's population suffers from some sort of chronic pain, which is far more difficult to control than, say, the pain of a cut or bruise. A great deal of effort has gone into the search for medically acceptable ways to control such pain, with few good answers emerging. Now medical researchers at the University of Michigan have directly demonstrated that transcranial electrical stimulation of a patient's brain causes the release of a natural opiate that dulls or eliminates the perception of pain.
