by University of California, Irvine The 90+ Study, one of the largest studies of its kind in the world, used cognitive assessment test scores from some of the more than 2,000 participants enrolled. The project has produced several significant findings regarding cognitive function, health and lifestyle habits in the oldest-old population information obtained during life. Credit:...
Combating Alzheimer’s and other neurodegenerative diseases by inserting healthy new immune cells into the brain has leaped reality. Neuroscientists at the University of California, Irvine and the University of Pennsylvania have found a way to safely thwart the brain’s resistance to them, vaulting a key hurdle in the quest. Their discovery about brain cells called microglia heralds...

The hypothesis, which was detailed in a...
by Bruce Goldman, Stanford University Credit: Pixabay/CC0 Public Domain Neuroscientist Tony Wyss-Coray, Ph.D., has spent 20 years unearthing and examining various molecules with neuroprotective and neurodegenerative properties. These molecules are found in or on different cell types in the brain and on the blood vessels abutting it, or floating in the blood and the cerebrospinal fluid...
Researchers from the University of Toronto have confirmed the critical role played by the brain’s hippocampus in updating our memories when those recollections are shown to be inaccurate. The hippocampus is part of the brain’s limbic system – the amalgam of neurological components that, among other functions, creates and retrieves our memories. Previous research demonstrated that...

Most observers perceive fleeting rays, beams, or lines emanating from the center that appear to be brighter than the background.
