Investigation of Neuronal Oscillations of the Working Memory System by Transcranial Rhythmic Stimulation
Cognitive Sciences and Technologies: From Neuron to Cognition
In the current study, we aim to investigate the underlying oscillatory mechanisms of the working memory (WM) system. We explore the idea that loading information to WM, retaining this information while holding off external distractors, and erasure of WM content are subject to the change of oscillatory frequencies. More specifically, alpha and beta oscillations were shown to play a role in the WM system as a stabilizer of the WM trace as well as a signature of inhibition of the distractors. We applied transcranial alternating current stimulation (tACS) while subjects performed WM task to investigate effects of different stimulation parameters on the behavioral outcomes of the task performance.
