Using Electricity to Increase Brain Activity

Using electric currents to boost brain function seems like something from a sci-fi movie, but in actual fact, it is something that is becoming more and more common practice around the world!

M.E.T FM’s producer Andrew Holroyd had a talk with Research Students Adraina Guo and Louis Barter who are studying the possible effects of low current direct stimulation of the pre-supplementary motor area of the brain and its role in inhibition processes. You can listen to the interview below!

Here’s some background on the study:

Inhibition is crucial for daily functioning. The study is aiming to gain a better understanding of the psychomotor inhibitory system, specifically the involvement of the pre-supplementary motor area (preSMA) in the inhibitory process. The study used a technique called transcranial direct current stimulation (tDCS), which is a form of non-invasive, safe, painless brain stimulation that uses direct electrical currents to stimulate parts of the brain. A very weak electrical current is passed through two electrodes placed over the head which supposedly increases brain activity. The effects generally last around an hour.

People who participated in the test will be asked to perform a response inhibition task on the computer. This study will require participants to complete two separate 2-hour experimental sessions, held at the same time of day, with an interval of at least two days between each session.
