A single control center for sleep and wake in the brain

Until now, it was thought that multiple brain areas were needed to control sleep and wakefulness. Neuroscientists from Bern have now identified one single control center for the sleep-wake cycle in the brain. The findings ...

Alzheimer's disease: How amyloid aggregates alter neuronal function

While the harmful effects of amyloid peptide aggregates observed in Alzheimer's disease are well established, the mechanism through which they act on brain cells remains ill-defined. Researchers from CNRS and universite de ...

Immune cells in the retina can spontaneously regenerate

Immune cells called microglia can completely repopulate themselves in the retina after being nearly eliminated, according to a new study in mice from scientists at the National Eye Institute (NEI). The cells also re-establish ...

Visual cues amplify sound

Looking at someone's lips is good for listening in noisy environments because it helps our brains amplify the sounds we're hearing in time with what we're seeing, finds a new UCL-led study.

Smelling your food makes you fat

Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight.

Stem cells may be the key to staying strong in old age

University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory ...

The extent of neuronal loss in the brain during MS

A study by researchers from Queen Mary University of London establishes for the first time the extent of neuronal loss in the brain of a person with MS over their life, and finds that demyelination may not be as good an indicator ...
