A shocking way to boost math skills

Note: this is cross-posted with my Education Blog.

The BBC reports:

Scientists in Oxford say applying an electrical current across the brain may be able to enhance your mathematical abilities.

The amount of electricity is tiny – one thousandth of an amp. The electrodes are placed at the back of the head over the parietal lobe. This is an area of the brain which is a crucial in acquiring mathematical skills. Those with dyscalculia, sometimes called maths dyslexia, often have abnormal function of the parietal lobe.

The researchers found that if the current flowed from the right of the brain to the left, then mathematical ability was enhanced. If it was reversed then it impeded learning, so that the volunteers scored no better in puzzles than a six year old.
