It will require the application of a very small current to specific parts of the brain in order to increase its activity, hence making the entire learning process a whole lot easier. This was performed by researchers from the University of Oxford as they studied the changing structure of the brain in stroke patients and in healthy adults. The brain, being an extremely flexible organ, is able to restructure itself, growing new connections and reassigning tasks to different areas, as it basically “heals” itself whenever damage occurs or a specific task is practiced.
This is one non-invasive technique that I don’t mind experiencing if I would end up with a better brain – but hopefully not with a huge forehead like the Leader in Incredible Hulk comics!
