Researchers look to the eye for insights about the brain

Researchers seeking to unravel the mysteries of how our amazingly complex brains do what they do, often start with the eye. The retina, the light-sensing tissue at the back of the eye has long been a model for scientists to explore how the brain works.

In the brain, the number of neurons in a network may not matter

A new study indicates that it may be possible to accurately characterize complete neural networks by recording the activity of properly selected samples of 50 neurons or less - an alternative that is much easier to realize.
