Diffusion Tensor Imaging (DTI) is an advanced form of magnetic resonance imaging (MRI) capable of mapping the direction of water motion in tissues. Fiber tracking is a specific method of assembling DTI data to study the three-dimensional architecture of the brain. This DTI fiber tracking image shows the brain of a living female cynomolgus monkey, collected as part of a study designed to determine whether cocaine use causes long-term changes to the brain’s structure and connectivity. Color indicates the direction that the axons (the brain cells’ long “arms”) are travelling: red is left to right, green is front to back, and blue is top to bottom.
