PODCAST: explore a study from Martin Luther University Halle-Wittenberg exploring how mild brain stimulation impacts decision-making speed and flexibility. Utilizing transcranial direct current stimulation (tDCS), a non-invasive method, researchers targeted the dorsolateral prefrontal cortex, a brain region critical for planning. The study found that anodal stimulation, which enhances brain activity, led to faster decisions, while cathodal stimulation, which suppresses activity, made participants adhere to previous choices. These subtle but statistically significant findings suggest tDCS can modulate cognitive flexibility under specific conditions, influencing how individuals coordinate simultaneous tasks.
