TRNS – A Brain Technique For Improving Math Skills
Researchers have had success targeting areas of the brain with non-invasive electrical stimulation. Subjects in the study
received TRNS – transcranial random noise stimulation – while undergoing arithmetic training. Results showed improvements in learning and subsequent performance on complex arithmetic tasks, specifically in enhanced speed of both calculation- and memory-recall-based arithmetic learning.
By using brain imaging techniques, the researchers were able to see responses in specific portions of the pre-frontal section of the brain, the area that is actually responsible for manipulating numbers. The results lasted. 6 months after the training, it was revealed that there were long-lasting behavioral and physiological modifications in the stimulated group as compared to the controls.
