Emotional Regulation and Decision Making: Modulation of Dorsolateral Prefrontal Cortex Excitability through tDCS.

The ability to regulate emotions is a crucial factor in how the brain balances risk and reward during decision making. Everyday choices are shaped not only by affective states but also by individual decision-making styles. This study examines how transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC), combined with emotion regulation (ER) strategies, influences choice behavior in healthy adults. Previous evidence indicates that downregulating negative emotions can reduce risky decisions, an effect linked to increased DLPFC activation.
