Electrically stimulating the brain to improve math performance

Oxford University scientists improved research subjects’ performance on math puzzles by applying a small electrical current to the part of the brain responsible for number sense. When re-tested six months after the study, the subjects continued to show improved performance on the math puzzles. While it remains to be seen whether other parts of the brain were affected by the electrical stimulation, the results of the study are suggestive and promising for people who suffer from dyscalculia (a brain disorder resulting in difficulty in making arithmetical calculations).
