Electrical noise stimulation of the brain is an intriguing area of research that has promise for improving a variety of cognitive tasks, including math learning. This approach is also known as transcranial electrical noise stimulation (tES) or stochastic resonance. The main idea is to deliver a controlled quantity of electrical noise to the brain via electrodes put on the scalp. In certain situations, this noise can modify neuronal activity and potentially improve brain function. 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 improve
