Bird’s-eye (axial) view of nerve fibers in a normal, healthy adult human brain

Bird’s-eye (axial) view of nerve fibers in a normal, healthy adult human brain. Brain cells communicate with each other through these nerve fibers, which have been visualized using diffusion weighted magnetic resonance imaging. Diffusion weighted imaging is a specialized type of MRI scan which measures water diffusion in many directions in order to reconstruct the orientation of the nerve fibers. Since these images are in 3D, colors have been used to represent the direction of the fibers: blue is for fibers traveling up/down, green for front/back, and red for left/right. These patterns of connectivity in the brain are being used to study brain development and developmental disorders such as dyslexia.Image and caption courtesy of Zeynep M.
