Brain activity intensity drives need for sleep

The intensity of brain activity during the day, notwithstanding how long we’ve been awake, appears to increase our need for sleep, according to a new study in zebrafish.

Alzheimer’s disease risk gene APOE4 impairs function of brain immune cells

A study carried out with a new human stem cell-derived model reveals that the most prevalent genetic risk factor of Alzheimer’s disease (AD), apolipoprotein E4 (APOE4), impairs the function of human brain immune cells, microglia. These findings pave th…

Physical fitness linked to better brain function

In the largest and most in-depth study of its kind, scientists confirm that physical fitness is associated with improved cognitive ability.

Routine sparring in boxing can cause short-term impairments in brain-to-muscle communication and decreased memory performance, according to new research.

How astrocytes help the brain process information

New research reveals that noradrenaline plays a key role in how astrocytes — star-shaped cells in the brain closely associated with neurons — track distinct information during behavior. The researchers found that astrocytes can integrate information …
