Electrical brain stimulation could boost math skills

If you're not good at math, electrical brain stimulation could make the difference.

It sounds crazy, and it's not being endorsed for that reason, but a new study reports transcranial direct current stimulation, or TDCS, helped improve the performance of adults with normal math abilities.

This involves stimulating specific regions of the brain with low-level electrical currents to enhance or reduce the activity of neurons.

The benefits lasted for up to six months.

Scientists say their aim is to eventually help children who experience difficulties with numbers. But more research is needed.
