Computational modeling and fMRI show the roles of brain regions in behavioral control
https://www.cell.com/neuron/abstract/S0896-6273(13)01125-2 John O’Doherty of the Caltech Brain Imaging Center has pinpointed areas of the brain—the inferior lateral prefrontal cortex and frontopolar cortex—that seem to serve as the “arbitrator” between model-based and model-free decision-making systems, weighing the reliability of the predictions each makes and then allocating control accordingly. Professor O’Doherty believes that this can lead to better…
