Investigating Mediodorsal Thalamus Representations Underlying Human Cognitive Flexibility

Participants will perform a set of computerized cognitive tasks designed to test working memory, cognitive control, and decision-making while undergoing high-resolution 7-Tesla functional MRI. These tasks require participants to maintain and update contextual information, switch between rules, and make value-based choices under changing conditions. The intervention is distinguished by its integration of advanced neuroimaging with computational modeling to identify how the mediodorsal thalamus and prefrontal cortex represent, update, and generalize context. This approach allows precise mapping of thalamocortical mechanisms that support flexible cognition and goal-directed behavior.
