Differences in White Matter (image) Carnegie Mellon University Share Print E-Mail Caption The left brain image shows the area of compromised white matter (blue area) among poor readers relative to good readers at the beginning of the study. The center brain image shows the area where the structural integrity increased (red/yellow area) among poor readers who received the instruction, and it is very similar to the initially compromised area. The right brain image shows that following the instruction, there were no differences between the good and poor readers with respect to the integrity of their white matter.
