A new optical system shows how decisions light up the brain

A technique called COSMOS will help researchers understand how our brains work and aid in the development of new drugs. The inventors have created an instructional website to help other researchers build their own relatively-inexpensive COSMOS systems.

The hidden pattern that drives brain growth

Using microscopy and mathematics, researchers have discovered the invisible pattern that growing neurons follow to form a brain. The technique could one day allow bioengineers to coax stem cells to grow into replacement body parts.
