We aim to advance the mechanistic understanding of pain anticipation by investigating how the human cortical motor system learns to prepare for aversive somatosensory events. In this study, we tracked how neural oscillations and corticospinal excitability reflect the acquisition and reversal of pain expectations. Using a Pavlovian conditioning task, participants learned to anticipate the occurrence of lateralized aversive shocks. Specifically, during acquisition neutral visual stimuli predicted shocks to either the left (CS+L) or right (CS+R) arm, while another stimulus (CS-) never predicted s

In the context of impulsive decision-making, delay discounting is a phenomenon observed when participants refer to the preference for a smaller reward sooner rather than a larger reward later in reward receipt. Previous neuroimaging findings showed that the dorsolateral prefrontal cortex (DLPFC) contributes to predicting the selection of larger-later over smaller-sooner rewards. However, recent studies on delay discounting offer mixed conclusions. This study aimed to examine how impulsive decision-making affects the signal transfer from the left DLPFC to the primary motor cortex (M1) by using
