Cocoa flavanols boost brain oxygenation, cognition in healthy adults

The brains of healthy adults recovered faster from a mild vascular challenge and performed better on complex tests if the participants consumed cocoa flavanols beforehand, researchers report. In the study, 14 of 18 participants saw these improvements a…

Scientists identify brain cells that help drive bodily reaction to fear, anxiety

Scientists have discovered that artificially forcing the activity of BNST cells in mice produced an arousal response in the form of dilated pupils and faster heart rate, and worsened anxiety-like behaviors. This helps illuminate the neural roots of emo…

A hunger for social contact

Neuroscientists have found that the longings for social interaction felt during isolation are neurologically very similar to the food cravings people experience when hungry.

Newfound ability to change baby brain activity could lead to rehabilitation for injured brains

Researchers have identified the brain activity for the first time in a newborn baby when they are learning an association between different types of sensory experiences. Using advanced MRI scanning techniques and robotics, the researchers found that a …

Magnetic brain waves to detect injury and disease

Researchers have designed a new Optically Pumped Magnetometer (OPM) sensor for magnetoencephalography (MEG). The sensor is smaller and more robust in detecting magnetic brain signals and distinguishing them from background noise than existing sensors. …

Memories create ‘fingerprints’ that reveal how the brain is organized

While the broad architecture and organization of the human brain is universal, new research shows how the differences between how people reimagine common scenarios can be observed in brain activity and quantified. These unique neurological signatures c…

Altered ‘coat’ disguises fatal brain virus from neutralizing antibodies

A genetic modification in the ‘coat’ of a brain infection-causing virus may allow it to escape antibodies, according to researchers. They say testing people for this and other viral mutations may help identify patients at risk for developing a fatal br…

Drug eases recovery for those with severe alcohol withdrawal

Scientists say a drug originally developed to treat high blood pressure can reduce severe withdrawal symptoms for patients diagnosed with alcohol use disorder.

Taking out the trash is essential for brain health

Researchers have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor defects attributed to neuronal accumulation of iron, …

Does air pollution increase women’s risk of dementia?

Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer’s disease, than women who live in locations with lower levels, according to a new study.
