For Motor Neurons, A Long Path to Find a Mate

Getting to the right place so the brain can work properly is the ultimate challenge for any neuron, but motor neurons have it especially tough.

Laminins Lay Down Tracks for Future Nerves

These proteins are representative of the boundary between the nervous system and the outside world.

Why Does the Brain Age?

Our brains change in subtle but measurable ways as we age, and neuroscientists have a few ideas about why that may be.

A Developing Fruit Fly Eye

With more than half of its tiny brain devoted to sight, the fruit fly is a favorite animal model for scientists studying the visual system.

How the Brain Changes With Age

As we age, we can see our hair gray and our skin wrinkle. Less obvious are the changes happening in our brains.
