Electric 'thinking cap' can help you learn faster, better

Psychologists show that it is possible to learn through the application of a mild electrical current to the brain, and that this effect can be enhanced or depressed depending on the direction of the current. The medial-frontal cortex is believed to be the part of the brain responsible for the “Oops!” response we have when we make a mistake.

 
Previous studies have shown that a voltage spike originates from this area of the brain milliseconds after a person makes a mistake.
 
Robert Reinhart, a Ph.D. candidate, and Geoffrey Woodman, assistant professor of psychology, wanted to test the idea that this activity influences learning because it allows the brain to learn from our mistakes.
 
Reinhart and Woodman set out to test several hypotheses, including: It is possible to control the brain’s electrophysiological response to mistakes.
 
Its effect could be intentionally regulated up or down depending on the direction of an electrical current applied to it. This bi-directionality had been observed before in animal studies, but not in humans.
 
Additionally, the researchers set out to see how long the effect lasted and whether the results could be generalized to other tasks.
 
Using an elastic headband that secured two electrodes conducted by saline-soaked sponges to the cheek and the crown of the head, the researchers applied 20 minutes of transcranial direct current stimulation (tDCS) to each subject.

So many new findings and potential application in neuroscience - lets hope that this device, a very curious " thinking cap" could have people with problems related to learning

The experiment indeed shows some potential. People tested made fewer errors and learned from their mistakes more quickly than they did after the sham stimulus. Reply

The hope is that the findings described in this article extend beyond the potential to improve learning. As they state"The process may also have clinical benefits in the treatment of conditions like schizophrenia and ADHD, which are associated with performance-monitoring deficits."

Recently, I found about that an epilepsy drug could help adults acquire perfect pitch and learn language like kids- another way to help learning?

The problem is much more challenging than what non-scientists assume. It seems that scientists not have an inkling regarding regarding the plasticity of human brain and learning processes Reply
