Interhemispheric effects of iTBS on the fronto-parietal network: Evidence from dual-site stimulation.

ABSTRACT: This study investigated the neuromodulatory effects of Theta Burst Stimulation (TBS) on resting-state functional connectivity (FC) following psychosocial stress induced by the Trier Social Stress Test (TSST). Given its key role in cognitive control and emotion regulation - processes highly relevant for rumination - we focused on the frontoparietal network. Across two studies, intermittent (iTBS) and continuous (cTBS) protocols were applied to the left Dorsolateral Prefrontal Cortex (DLPFC; study 1) and right Ventrolateral Prefrontal Cortex (VLPFC; study 2) prior to stress induction. Functional Near-Infrared Spectroscopy (fNIRS) was used to assess neural changes. A total of 88 (study 1) and 89 (study 2) healthy participants were recruited, balanced for low and high trait rumination. Each pa
