New roles found for Huntington's disease protein

A Duke University research team has identified a new function of a gene called huntingtin, a mutation of which underlies the progressive neurodegenerative disorder known as Huntington's Disease.

With these neurons, extinguishing fear is its own reward

When you expect a really bad experience to happen and then it doesn't, it's a distinctly positive feeling. A new study of fear extinction training in mice may suggest why: The findings not only identify the exact population ...

Finding the genes that turn on Japanese encephalitis

Investigators have identified the specific genes that become overactive as a result of nerve cell infection with Japanese encephalitis virus. The genes activate cell receptors and signaling proteins that attract immune cells ...

Serotonin is a master regulator of neuroregeneration

Neuroregeneration entails not only neurogenesis, but also regrowth of lost connections and birth of non-neuronal cells. While adult neurogenesis in humans is only known to occur definitively in a few precisely circumscribed ...

Protein signposts guide formation of neural connections

The brain's complex tangle of interconnected nerve cells processes visual images, recalls memories, controls motor function, and coordinates countless other functions. A major goal of neuroscience is understanding how the ...
