Brain's left hemisphere picks up peripheral noise

Our brain is very good at picking up speech even in a noisy room, an adaptation essential for holding a conversation at a cocktail party, and now we are beginning to understand the neural interactions that underlie this ability.

Biomarkers for Alzheimer's can be trusted in clinical trials

The best-established biomarkers for Alzheimer’s disease have a low natural variation over two years. The results speak for the inclusion of these biomarkers in clinical trials of novel drugs against Alzheimer’s disease.

Scientists zero in on the cellular machinery that enables neurons to fire

Toy robots with removable body parts - you probably had fun swapping their heads, imagining how it would affect their behavior. Scientists supported by the National Institutes of Health have been performing similar experiments on ion channels - pores in our nerve cells - to sort out the channels' key functional parts.

Hormone orexin links sleep, hunger and metabolism

While investigating how the hormone orexin might control sleep and hunger, researchers at UT Southwestern Medical Center have discovered, to their surprise, that it activates a protein, HIF-1, long known to stimulate cancerous tumor growth.

New drug may restore memory with Alzheimer's disease

A 2006 study by MetLife found that adults over age 55 fear Alzheimer's disease more than cancer, and with good reason. Alzheimer's creeps up on patients and their families, robbing more than half of all Americans over age 85 of their memory and ability to care for themselves.
