Electric shock enhances human performances: Study suggests

London: A new study has suggested that passing small electric currents through the brain can lead to enchanced academic performance and boost people’s learning.

Known as “Transcranial Direct Current Stimulation”, the method has earlier been used to treat cognitive impairment among stroke and brain injury patients and those with learning difficulties, the Telegraph reported.

Experts from the University of Oxford’s Department of Experimental Psychology conducted experiments on healthy volunteers and checked how well they performed in mathematical problem solving and linguistic tasks before and after undergoing the shock treatment.

Electrodes were strapped to the head to deliver small electric currents to certain parts of the brain for short bursts up to 20 minutes.

Results showed the treatment improved the volunteers’ vision, decision-making, problem-solving, mathematical, language, memory, and attention capabilities.

The positive effects can last up to 12 months, the researchers said.

“The idea is to stimulate the brain in order to make it easier to learn new information such as maths. What we find with adults is that the improvement is not only in maths but actually in language, attention and decision making – they not only become better for a short time, but for long periods,” said Roi Cohen Kadosh, who led the research.
