Do you have trouble with math? One study says they may have a way for you to improve–electric shock.
According to CBS News, a new study finds that an electric jolt to the brain actually helped people perform calculations faster than those who did not get the shock. They say these skills seemed to last long-term.
During this experiment, researchers used a new method of electrical stimulation called transcranial random noise stimulation. They used it on the part of the brain that does math skills.
