Single high-frequency repetitive transcranial magnetic stimulation and intermittent theta pulse stimulation promote working memory behavior in participants: An event-related potential study

Single sessions of HF-rTMS and iTBS on the L-DLPFC specifically enhanced working memory performance, with no significant effects on executive function and visuospatial attention. Both true stimulations elicited more negative N2 in the frontal and central channels during the 2-back paradigm, suggesting increased recruitment of cognitive resources from these brain areas. Although iTBS and HF-rTMS improved working memory behavior, iTBS's shorter stimulation time suggests it may have greater potential for clinical applications in terms of time-benefit costs.
