Rainbow Brain Map Reveals Grid-Like Pattern
[Image: 3AD9_4F7989E2.jpg]


To the unaided eye, the most striking feature of the human brain is its squiggly pattern of bumps and grooves. But within those curves is a latticework of nerve fibers that cross each other at roughly right angles (above), according to a study published March 30 in Science.

The researchers used a recently-developed method called diffusion spectrum imaging to infer the position of nerve fibers in the living human brain from the way water flows through and around them. These scans revealed an orderly weave of fibers — a much simpler organization than many scientists would have suspected.

So the Information Super Highway is purple.

Cool!

Who knew.

Scientists have created the first genetic “atlas” of the human brain, and the result is a very pretty Skittles-esque map of the brain as a rainbow. A brainbow.

It’s more than just a fun visual. The atlas reveals a whole new way of organising the cerebral cortex — the 2mm-thick sheet of neural tissue that wraps around the brain. This thin envelope contains multiple layers of interconnected neurons with key roles in memory, attention, language, cognition and consciousness.

Other brain maps organise the brain by differences in tissues and their function. This genetics-based depiction organises brain activity in a new way and it could help scientists study age-related changes in brain structure, as well as diseases and disorders associated with cognitive function.

To make the new map, the team of scientists used magnetic resonance imaging to look at the brains of 406 adult twins who were already part of the Vietnam Era Twin Registry, an ongoing study of cognitive ageing. Twins share 100 per cent of their genes, so by comparing MRIs from sets of twins, the scientists could compare aspects of their cortical structure. The scientists figure that the matching portions were likely dictated by genes and any variations in the twins’ cerebral cortices were caused by differences in the their environments.

That is a nice, neat wiring job.
