Recent studies have looked at a new method of brain stimulation that makes neurons function more efficiently. Transcranial random noise stimulation-or TRNS-is performed by using electrodes on the surface of the scalp to apply random electrical noise to certain areas of the brain. This new technique can be used to help those with learning difficulties, strokes and neurodegenerative illnesses. In a study at Oxford University, researchers compared the math skills of those who had TRNS and those who did not. They computed simple equations like 32-17+5=20. There were no immediate differences but when they were brought back for follow ups 6 months later, noticeable improvements were found in the subjects who had TRNS. Researchers then concluded that TRNS improved the speed at which affected areas of the brain used their supplies of oxygen and nutrients.

We are currently studying the human body including the brain. The brain requires oxygen and blood to carry out its countless tasks and responsibilities. TRNS increases neuron's efficiency, specifically by them using oxygen and nutrients. Increasing a neuron's efficiency has proven to be beneficial, not only for increasing math skills but the potential to help those with strokes and other neurodegenerative diseases. Overall this new treatment shows potential to become a functioning and useful treatment.
