Transcranial Random Noise Stimulation is More Effective than Transcranial Direct Current Stimulation for Enhancing Working Memory in Healthy Individuals: Behavioural and Electrophysiological Evidence

Transcranial direct current stimulation (tDCS) has been shown to improve working memory (WM) performance in healthy individuals, however effects tend to be modest and variable. Transcranial random noise stimulation (tRNS) can be delivered with a direct-current offset (DC-offset) to induce equal or even greater effects on cortical excitability than tDCS. To-date, no research has directly compared the effects of these techniques on WM performance or underlying neurophysiological activity.
