The Brain Unveiled: A New Imaging Method Offers A Spectacular View of Neural Structures
This story is from the category The Brain
Date posted: 27/10/2008
A new imaging method that offers an unprece?dented view of ?complex neural structures could help explain the workings of the brain and shed light on neurological diseases. Diffusion spectrum imaging, developed by neuroscientist Van Wedeen at Massachusetts General Hospital, analyzes MRI data in new ways, helping scientists map the nerve fibers that carry information between cells.
Neural fibers in the brain are too tiny to image directly, so scientists map them by measuring the diffusion of water molecules along their length. The scientists first break the MRI image into "voxels," or three-dimensional pixels, and calculate the speed at which water is moving through each voxel in every direction.
