McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life. A new study found that variations in ...

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and the nervous system.

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

A long-standing goal of neuroscience is to understand how molecules and cellular structures on a microscale give rise to communication between brain regions at the macroscale. A study now identifies, ...

Decades of exercise research data support the common view that steady workouts over the long haul produce not only physical benefits but also improved brain function. But what about single bursts of ...

Shew explained that physicists first developed a deep understanding of criticality as a way to describe magnets and other materials. Around the turn of the 21st century, these ideas were expanded to ...

The session explored how long-term use of substances affects thinking, behaviour, and everyday decision-making and why ...

Chewing might help reduce stress responses in certain people because it can lower tension and help the body move toward a ...

Using a range of brain measurement techniques researchers assessed the effects of a single, high dose of psilocybin in ...
