White matter fibres. Coloured diffusion tensor imaging (DTI) scan of a section through a healthy brain showing the orientation of white matter fibres. An outline of the skull is seen around the brain. Fibres running between right and left are red,those running between the front and back are blue and those running between the interior and exterior are green. White matter consists of bundles of nerve fibres. The fibres transmit nerve signals between brain regions and between the brain and the spinal cord. DTI scans show the diffusion of water along white matter fibres,allowing their orientations and the connections between brain regions to be mapped | |
