Researchers identify a molecule critical to functional brain rejuvenation

Recent studies suggest that new brain cells are being formed every day in response to injury, physical exercise, and mental stimulation. Glial cells, and in particular the ones called oligodendrocyte progenitors, are highly responsive to external signals and injuries. They can detect changes in the nervous system and form new myelin, which wraps around nerves …

What Happened During the 1921 Tulsa Massacre, One of the Worst Episodes of Racial Violence in U.S. History

In February 1915, Thomas Dixon, author of popular novel The Clansman, and D.W. Griffith, the director who adapted the book into the film Birth of a Nation, lobbied then-president Woodrow Wilson for a screening at the White House. The two were sure their story would get a warm reception from the “well documented racist” and …

An ‘atlas’ of the brain’s choroid plexus across the lifespan

Once viewed merely as a producer of the cerebrospinal fluid (CSF) bathing the brain and spinal cord, the choroid plexus is now known to be a key player in brain development and immunity. These fronds of brain tissue, located in the CSF-filled brain cavities known as ventricles, secrete instructive cues into the CSF to regulate …
