Topic: value encoding

Every day, we make decisions between multidimensional options. Learning each option’s value by simultaneously attending to all its dimensions is challenging. However, humans navigate this complexity by selectively focusing on relevant information, making real-world, multidimensional reinforcement learning (RL) tractable. Neuroimaging has identified correlates of attention and value learning in the lateral prefrontal (LPFC) and orbitofrontal (OFC) cortex, respectively, yet these methods fall short in elucidating the physiological mechanisms by which these regions coordinate during multidimensio

Cognitive flexibility is necessary for efficient disengagement from a previous task or reconfiguring and implementing new responses to a novel demand. The orbitofrontal cortex is associated with value encoding and is crucial for flexibility to switch behaviours in front of unexpected outcomes. However, the neuronal mechanisms behind such flexibility to modify the encoded value are unknown. We aim to determine the dynamical mechanisms of orbitofrontal neuronal circuits involved in value-based decisions across different environmental contingencies. For this purpose, we perform large-scale electr
