Mapping The Brain
The future gets closer:
In this new study, a team of neuroimaging researchers led by Hagmann used state-of-the-art diffusion MRI technology, which is a non-invasive scanning technique that estimates fiber connection trajectories based on gradient maps of the diffusion of water molecules through brain tissue. A highly sensitive variant of the method, called diffusion spectrum imaging (DSI), can depict the orientation of multiple fibers that cross a single location. The study applies this technique to the entire human cortex, resulting in maps of millions of neural fibers running throughout this highly furrowed part of the brain...
"We found that the core, the most central part of the brain, is in the
medial posterior portion of the cortex, and it straddles both
hemispheres," Sporns said. "This wasn't known before. Researchers have
been interested in this part of the brain for other reasons. For
example, when you're at rest, this area uses up a lot of metabolic
energy, but until now it hasn't been clear why."
