The goal of NS2 is to translate high spatial and temporal resolution brain imaging, fMRI, MEG, and noninvasive brain stimulation into viable solutions for training soldiers and intelligence professionals to help them with real-time decision making and actions that avert injury and trauma. Noninvasive brain stimulation, specifically transcranial direct current stimulation (TDCS), is being used to attempt to influence the learning process, perhaps increasing the speed of learning or improving retention. TDCS utilizes scalp electrodes to deliver low amplitude direct currents to localized areas of the cerebral cortex (the superficial part of the brain), thereby modulating the level of excitability, or, put another way, increasing or decreasing the probability that neurons will talk to each other. “Even though TDCS has been applied to humans safely for decades, we are just beginning to learn how it helps to accelerate the learning process. Within the next couple of years, I expect great progress toward this goal,” says researcher Dr. Michael Weisend.
