How Brain See
At the micro scale the brain is a mess; a thick tangle of nerve cells connected at synapses. Mapping just a tiny portion of this mess, a few hundred cells, is a huge challenge. You have to wonder if it’s worth the effort. But seeing exactly how brain cells are wired together is giving us new insights into brain function. The researchers who made the 3D maps in this video discovered a new type of cell and worked out how insects see movement. If you’ve ever tried to swat a fly you’ll know how good they are at sensing motion!

Neurology and the Passion for Art

Ramachandran, director of UCSD’s Center for Brain and Cognition has studied how the brain perceives works of art and thinks he may know the answer to this intriguing question.
