Brain waves predict speed of learning

There's a lot of debate about the significance and application of neuroscience research in learning and other fields. While neuroscience most certainly contributes greatly to our understanding of how we learn, I take a lot of research with a grain of salt: much of it simply tells us what we already know. But sometimes I come across a piece of research that really stimulates my brain waves and which may lead to genuine learning interventions and applications. And this is one such piece.

Scientists report that they can predict who will learn a video game most quickly by recording their brain waves. Using EEG, they measured brain oscillation in non-experienced game players and found that greater oscillations at the front of the brain  (in the alpha spectrum) predicted speed of learning. The oscillations are caused by electrical activity across millions and billions of neurons. When our alpha brain waves oscillate between 8 and 12 Hz, its known that our brain remains in a relaxed, but alert state. Increased alpha brain wave activity appears to have many benefits for people, including relaxation, but this studies shows that it's directly linked to learning in a truly immersive environment = games. Alpha waves are increased through positive feedback, which has obvious implications for learning and teaching. Researchers believe that everyone could benefit from tools and interventions that would increase alpha brain waves. It's known that meditation and yoga increase alpha waves. You could also try these glasses.

(Note: Other studies indicate that the volume of certain structures in the brain also predict learning ability in games so clearly it's multifactorial.)

The brain works through a fascinating marriage of chemistry and electricity. Experiments in applying electricity to the brain have had incredible results. Electrical brain stimulation can fundamentally change the way we think and will no doubt lead to battery-operated cognitive enhancement in the near future. In fact, research shows that such a 'creativity cap' could produce savant-like abilities in anyone. The questions around these discoveries are myriad. How will neuro-enhancement affect education and competition? What will constitute being 'the best' or 'talented' at anything? What will the side effects be for the brain? Exciting and controversial times lie ahead.
