Over the past years we have devoted significant efforts to implement routine, systematic motion compensation for brain PET studies at our center. The following work, just published in Current Biology (led by our collaborator, the late Dr. Yantis), was only able to arrive at significant correlations between value-based distraction and PET-measured dopamine release after inclusion of motion compensation. We are quite motivated by these positive findings.
