Diffusion tensor tractography

Tractography is used to model anatomical connections inside a living brain. It involves a specialised type of magnetic resonance imaging (MRI) called diffusion tensor imaging, which uses magnetic fields and radio waves to track the movement of water molecules. This information is then used to digitally reconstruct the orientation of fibres in the brain, providing an insight into how different parts of the brain use this network of pathways to communicate with each other.
