Scientists have experimentally proven: electrical stimulation brain repeatedly enhances mathematical abilities.
Dr. Roi Cohen Kadosh, neurophysiologist Department of Experimental Psychology, University of Oxford (Oxford University’s department of experimental psychology) started experimenting three years ago. And then through electrodes put on the heads of 15 volunteer students, demonstrated: weak electric shocks lead to to what volunteers begin to perform faster and more accurately in the mind arithmetic operations.
The effect of electrical stimulation lasts about six months. Later, to get smarter, you must again apply to the DC source

In the current experiments, 50 volunteers participated. Half of them were stimulated by electricity for five days, while were trained. About 20 minutes each during the 45-minute lesson. The other half was tricked – they inflicted a light electric shock, and then immediately turned off the electricity.
After stimulation – real and false – the volunteers decided already not arithmetic, but much more complex mathematical problems.
Result: stimulated by current acquired new knowledge in 5 times faster than their non-electrified counterparts. And the tasks were solved 30 spans faster and more accurately. Moreover, an amazing effect persisted for about six months.
Kadosh believes that he has found a way that allows without harm to make a person much more healthy – at least in areas of mathematics. Someone, maybe, after an electric shock to the head generally turn into a genius. And as Perelman will prove some tricky theorem.
However, the experimenters did not initially target their research on ordinary people – wanted to help “flawed”, for example, victims of a stroke. Or those who are not naturally strong in math. Such, according to statistics, every fifth.
Scientists have presented the results of their research in the journal Current Biology. And they admitted that they still cannot explain them. Maybe, electrical stimulation simply improves blood supply to the brain or nutrients. Or maybe the mechanism is much more complicated.
In the future, Kadosh and colleagues would like to know whether it is possible to using current to strengthen other abilities, stimulating corresponding parts of the brain? Suddenly, putting on electrodes, people will turn into virtuoso musicians. Or outstanding artists. Or in ingenious chess players. Or even soccer players who get on goal.
