Zap the brain with electricity to speed up mental maths

Are you bad at sums? Never remember your times tables? Now you can simply zap your brain with a pulse of electricity to make mental arithmetic a whole lot easier.

In 2010, Roi Cohen Kadosh at the University of Oxford and colleagues showed that a technique called transcranial direct current stimulation could help people to learn and process symbols representing numbers.

Now, his team has shown that a similar procedure can help people improve their mental arithmetic – and crucially, the effects are long lasting.

This non-invasive procedure could help children with learning difficulties, or be used in the rehabilitation of people after a stroke. It might even be able to help other people improve their mental athleticism.
