Humans adapt flexibly to their environment to achieve goals efficiently and avoid harmful outcomes through a process referred to as cognitive control. Employing cognitive control effectively requires inferring the type and intensity of control likely needed in a given situation and deploying it proactively. In this symposium, we aim to advance our understanding of the mechanisms underlying the recruitment of cognitive control by integrating insights on how external and internal modulators shape control processes. First, Jana Tegelbeckers will outline the neurocognitive effects of sleep deprivation on cognitive control mechanisms. Second, Debbie M. Yee will present findings on serotonergic modulation of stressor controllability and cognitive control allocation in a novel stress paradigm. Third, Gerhard Jocham will discuss cholinergic influences on reinforcement learning and cortical dynamics under uncertainty. Finally, Camila Agostino will highlight how multi-regional transcranial ultrasound stimulation affects neural signatures of conflict monitoring and error processing.
