Video: Human brain scan

This colorful brain scan is a 3-D model created by tractography, which uses data collected with diffusion weighted MRI to map the brain's white matter. Each line represents a bundle of nerve fibers wrapped in a myelin sheaths, ...

Thicker nerve fibers enable faster reactions in mice

In order for organisms to react swiftly to stimuli in their environment, they need rapid and precise transmission of nerve impulses along neural extensions known as axons. Whereas some invertebrates have developed very thick ...
