I wasn't great at maths at school. But if I'd been given a treatment called transcranial random-noise stimulation, or TRNS, I might have got better grades.
A new study has found that students who received regular TRNS became faster at doing simple maths tasks. And the amazing thing is, the effect was long term: even six months after receiving the stimulation, they still performed better than students who didn't get the same treatment.
It's a totally painless process, apparently. Would you be up for it?
