Scientists have long believed that glioblastoma multiforme, the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. Researchers found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.
The brain’s key “breeder” cells secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.
New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels.

Researchers attempt to improve robot behavior by means of perception models closer to those of humans. One of the experiments involves a robot simulation in which an agent has to discriminate between what we could call an acne pimple and a bite or lump on the skin.
The Who asked “who are you?” but Dartmouth neurobiologist Jeffrey Taube “where are you?” and “where are you going?” Taube is not asking philosophical or theological questions. He is investigating nerve cells in the brain that function in establishing one’s location and direction.
Stem cell study may help to unravel how a genetic mutation leads to Parkinson's symptoms. By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation, researchers identified damage to neural stem cells as a powerful player in Parkinson's disease.
A European team of scientists have built the first atlas of white-matter microstructure in the human brain.
An inexpensive, five-minute eye scan can accurately assess the amount of brain damage in people with the debilitating autoimmune disorder multiple sclerosis (MS), and offer clues about how quickly the disease is progressing.
If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to research.
