On the left, the arcuate fasciculus is highlighted in the brain. On the right, the colors of the arcuate fasciculus indicate the level of randomness of water diffusion within the structure, which reflects the integrity of white matter tracts and fiber organization. Higher fractional anisotropy (FA) scores indicate higher tract integrity. The MIT team found that those values correlated with scores on a verbal task known as blending words (BW).
