White matter fibres. Computer enhanced 3D diffusion spectral imaging (DSI) scan of the bundles of white matter nerve fibres in the brain. The fibres transmit nerve signals between brain regions and between the brain and the spinal cord. Diffusion spectrum imaging (DSI) is a variant of magnetic resonance imaging (MRI) in which a magnetic field maps the water contained in neuron fibers, thus mapping their criss-crossing patterns. A similar technique called diffusion tensor imaging (DTI) is also used to explore neural data of white matter fibres in the brain. Both methods allow mapping of their Stock Photohttps://www.alamy.com/licenses-and-pricing/?v=1https://www.alamy.com/stock-photo-white-matter-fibres-computer-enhanced-3d-diffusion-spectral-imaging-170920014.htmlRFKX2266–White matter fibres.

White matter fibres. Computer enhanced 3D diffusion spectral imaging (DSI) scan of the bundles of white matter nerve fibres in the brain.

Diffusion spectrum imaging (DSI) is a variant of magnetic resonance imaging (MRI) in which a magnetic field maps the water contained in neuron fibers, thus mapping their criss-crossing patterns.

Pathological phosphorylation (yellow) of Tau proteins (orange) by kinases (blue-purple) affect nerve cells in what is called a neurofibrillary tangle. This illustration shows the transport of synaptic vesicles (red-blue spheres) being interrupted. The tau proteins also affect microtubles (orange cylinders). A neurofibrillary tangle consists of abnormal aggregates and insoluble fibres of the protein tau. Tau protein is an abundant neural protein, aggregations of which are thought to play a role in Alzheimer's disease and other neural disorders.
