"This computer generated image is called DTI (diffusion tensor imaging) color map of the brain. In neuroscience, the tractography is a 3D modeling technique used to visually represent neural tract using data collected by DTI (a special MRI method).The tractography used special technique of MRI, and computer based image analysis. The results are represented in two and three-dimensional images.This technology has been used to evaluate the white matter connectivity of the brain."
