Neurons — the nerve cells that make up the brain and nervous system — look different from all other cells in the body. And from one another.

By combining brain imaging techniques with computer software that can detect brain activity, neuroscientists are getting a look into how the brain perceives, decides, and remembers.

It’s a very small worm — only one millimeter in length — with a big name: Caenorhabditis elegans. But few organisms have made as large a contribution to science.

Scientists have identified some of narcolepsy’s underlying genetic and neurobiological causes — discoveries that reveal biological mechanisms of sleep disorders and potential treatments.

Stroke is a leading cause of disability around the world and the fourth leading cause of death. But what most people do not know is the same habits that help protect the heart may safeguard the brain.

Decision-making is such a seamless process we’re usually unaware of it — until our choice results in unexpected consequences. Then we wonder, “Why did I choose that option?”

By studying how baby birds learn to sing scientists hope to gain insight into the neural mechanisms by which humans learn to speak.

Mind over matter is no longer the stuff of science fiction alone. Brain-computer interface technology now enables severely physically disabled people to independently compose and send emails.

The ability to instinctively and immediately understand what other people are experiencing has long baffled neuroscientists, psychologists, and philosophers alike. Research now suggests a fascinating explanation: brain cells called mirror neurons.

As scientists unlock more of the neurological secrets of the bilingual brain, they're learning that speaking more than one language may have cognitive benefits that extend from childhood into old age.
Cells known as glia (Greek for “glue”) were long believed to provide nothing more than support to nerve cells.

Scientists used to think glia cells were the nervous system’s supporting players, helping keep brain cell communication in working order. But recent studies suggest glia play a more vital role.

Everybody gets thirsty. The urge to drink fluids is a natural instinct regulated by a negative feedback loop between the brain and other organs in the body.

Neurons transmit signs to your brain every millisecond of every day, and facilitate almost everything you do. But what happens when this critical process goes wrong?

It can be frustrating to be unable to recall information when you need it. But forgetting is actually a good thing.

We all want to age well. Exercise, eating right, and avoiding stress help maintain a healthy body as we age, but what about the brain? New research indicates these same strategies also promote brain health.

Why do some people enjoy the taste of broccoli while others find it bitter and unpleasant? Neurobiological and genetic sources of taste preferences can influence eating habits — and health.
