Youngest brain tumor patients have significantly poorer outcomes than older pediatric patients

A researcher has found, through extensive data analysis, that the youngest patients with brain tumors — those ages birth to 3 months — have about half the five-year survival rate as children ages 1 to 19.

‘Switching off’ specific brain cells protects against stress

Researchers have discovered a small group of brain cells in the claustrum that controls stress-induced anxiety behaviors. Manipulating the activity of these cells also altered anxiety-related behaviors, which suggested that these claustrum cells are ke…

New strategy reduces brain damage in Alzheimer’s and related disorders, in mice

Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau. A study has now shown that targeting astrocytes — an inflammatory cell in the brain — redu…

Scientists see what research participants picture in their mind’s eye

Researchers have found that the meaning of what a person is imagining can be determined from the pattern of their electrical brain activity, even if what they are imagining is different from what they are looking at, and that real-time feedback makes t…

How coronavirus triggers immune response in brain

A new study describes how the spike protein used by the coronavirus to enter human cells can have a similar effect on the brain’s immune cells as it does with the rest of the body.

Large study on traumatic brain injury highlights global inequality in causes and treatment

A large study examining the surgical management of traumatic brain injuries highlights regional inequalities in both major causes and treatment of such injuries.

Scientists identify neurons in the brain that drive competition and social behavior within groups

In mice, social ranking in a group was linked to the results of competition, and certain neurons in the brain stored this social ranking information to inform decisions. Manipulating the activity of these neurons could increase or decrease an animal’s …

Largest ever psychedelics study maps changes of conscious awareness to neurotransmitter systems

In the world’s largest study on psychedelics and the brain, a team of researchers have shown how drug-induced changes in subjective awareness are anatomically rooted in specific neurotransmitter receptor systems.

What regulates the ‘glue’ needed for nerve repair?

Researchers have identified a molecule essential for regulating the repair of injured nerves, which could help people recover from nerve damage.

Researchers may have unlocked the blood-brain barrier

The brain is composed of billions of neurons — vulnerable cells that require a protective environment to function properly. This delicate environment is protected by 400 miles of specialized vasculature designed to limit which substances come into con…
