Simultaneous MRI and PET Images Showing Interaction between Brain Networks (IMAGE)
Caption
In the MR image (vertical slice), warmer colors show activation within the frontopartietal control network (FPCN), and cooler colors show deactivation within the default network (DN) during working memory. The PET scan (horizontal slice) reveals the density of D1 dopamine receptors along the outer cortex (purple) and in the striatum (green), a subcortical area containing many D1 receptors. The density of D1 receptors in the cortex, but not in the striatum, predicted the extent to which the FPCN and the DN became disconnected during working memory.
