Keeping Time in the Brain

Astrocytes are star-shaped cells found in the brain and spinal cord previously thought of as just supporting neurons in regulating circadian rhythms. The latest research shows the cells can actually lead the tempo of the body’s internal clock and are able to control patterns of daily behaviour in mammals. Credit: Bruno Pascal / Wikicommons.



New Role for Microvessels in Spinal Cord Injury


Previously unidentified roles have been established for endothelial cells: they engulf myelin debris following spinal cord injury, and contribute to the progression of inflammation, angiogenesis, and possibly, fibrotic scar formation.


When Memory Loss Could Just Be Hearing Loss


A recent study published in the Canadian Journal on Aging, found that the majority of participants being evaluated for memory and thinking concerns and potential brain disorders had some form of mild to severe hearing loss, but only about 20 per cent of individuals used hearing aids. Among the participants, a quarter of them did not show any signs of memory loss due to a brain disorder.


Neurofilament Light Change Dynamics: Alzheimer's Diagnostics Progress


A simple blood test reliably detects signs of brain damage in people on the path to developing Alzheimer’s disease – even before they show signs of confusion and memory loss, according to a new study from Washington University School of Medicine in St. Louis and the German Center for Neurodegenerative Diseases in Germany.
