Sleep disturbances linked to genetic Alzheimer's risk
A person's sleep patterns could be an early sign of Alzheimer's disease, a new study says. A greater number of micro-awakenings during sleep is linked to a greater genetic risk for Alzheimer's, researchers report in the journal ...

Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice
Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...
Quitting alcohol changes the brain and can increase the risk of compulsive drinking—new research in mice
For some, abstaining from alcohol can subsequently increase compulsive drinking. Our research team found that, in abstaining mice, this urge to drink is preceded by changes in the activity of a particular brain region, pointing ...

Brain cancer cells exploit normal nerve signaling to multiply and invade, new study finds
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common form ...
Brain circuit keeps tabs on what just happened to aid judgment of what's happening now
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it. On the one hand, it has to be open to whatever new sensory information may come its way, ...
