Plaques and the Resting Brain (IMAGE) Washington University School of Medicine Caption Scientists at Washington University School of Medicine in St. Louis have shown that brain cells in the default mode network, highlighted in blue on the left, communicate with each other more often than other brain areas. This may help explain why these same areas are often hit first by Alzheimer's plaques, which are highlighted in red in the brain images on the right.
