According to a new study from the Universities of Surrey and Oxford, Loughborough University, and Radboud University in the Netherlands, electrical noise stimulation can aid in improving arithmetic learning in those who struggle with the subject. Researchers explored the effect of neurostimulation on learning in this one-of-a-kind study. Despite the increased interest in this non-invasive procedure, little is known about the neurophysiological changes that occur as a result of it and their impact on learning. Electrical noise stimulation over the frontal portion of the brain boosted the mathematical abilities of those whose brains were less aroused (by mathematics) before the
