Some people who got the electric stimulation (1)______________________________.Others were significantly worse, depending on how the current was applied.
Cohen Kadosh says the electric current apparently affects brain chemistry in a way that (2)______________________________, a feature called plasticity. "This is what we want eventually to do in these cases, where people have some problems to learn correctly".
This kind of stimulation may affect more than just numerical skill. Cohen Kadosh says other researchers are studying how it might be used to alleviate pain, or help restore speech after a stroke, to name just 2.
This is still just a laboratory finding, but (3)______________________________, persisting for at least 6 months. Cohen Kadosh and his team are patenting the process and he says electric brain stimulation might one day be used to restore abilities lost through illness or may be just help a prospective engineering student improve her math skills.
**** Hidden Message ***** showed significantly better performance in the tests
makes the brain cells more adaptable
the effective 6 20 minutes sessions is long lasting showed significantly better performance in the tests
