![]() Their development, published on December 18 in Scientific Reports, gives researchers more confidence in using the technique to untangle the human brain's wiring and to better understand the changes that accompany neurological or mental disorders such as Parkinson's or Alzheimer's disease. Scientists in Japan's brain science project have used machine intelligence to improve the accuracy and reliability of a powerful brain-mapping technique, a new study reports.

Fiber tracking algorithms then use this information to estimate the path of the nerve fibers. (Right) The diffusion MRI measures the direction that the water molecules diffuse at each point in the brain, as illustrated by ellipsoids here. (Left) MRI scanners, like the one pictured at RIKEN Center for Brain Science, can be used to non-invasively map the brain by analyzing the diffusion of water molecules.
