Transient Modulation of Working Memory Performance and Event-Related Potentials by Transcranial Static Magnetic Field Stimulation over the Dorsolateral Prefrontal Cortex

Transcranial static magnetic field stimulation (tSMS) can modulate human cortical excitability and behavior. To better understand the neuromodulatory effect of tSMS, this study investigates whether tSMS applied over left dorsolateral prefrontal cortex (DLPFC) modulates working memory (WM) performance its associated event-related potentials (ERPs). Thirteen healthy participants received or sham DLPFC for 26 min on different days. The performed a 2-back version n-back task before, during (20 after start stimulation), immediately after, 15 stimulation. We examine reaction time correct responses, d-prime reflecting WM performance, N2 P3 components ERPs. Our results show that there was no time. reduced, latency prolonged tSMS. These findings indicate affects electrophysiological signals, which be considered an important step toward greater understanding use in studies higher-order cognitive processes.
