Maiuri, MPH, CHES Mayo Clinic researchers mapped how the measles virus mutated and spread in the brain of a person who succumbed to a rare, lethal brain disease. New cases of this disease, which is a complication of the measles virus, may...
October 16, 20235:01 AM ET Jon Hamilton Scientists are one step closer to understanding the 170 billion brain cells that allow us to walk, talk, and think. A newly published atlas offers the most detailed maps yet of the location, structure, and, in some cases, function of more than 3,000 types of brain cells. “We...

Recent research found early disease signs in cell culture models of early human brain development, raising the possibility that the disease has its origins much earlier...
Scientists suggest patient’s own cells could be grown in the lab and used to repair stroke or trauma injuries In the study, human brain tissue was transplanted into the brains of adult rats.

Neurons are stained green. Credit: F. Sanchís Calleja, A. Jain, P. Wahle / ETH Zurich The human brain is probably the most complex...
The human brain is an incredibly complex organ that is inherently dynamic. Even viewing a simple, static image on a screen unleashes a vast network of neural activity in our brains. But the invasive nature of the techniques necessary for examining such activity means that scientific studies frequently focus on non-human subjects. But now an international research...

Credit: Arianna Polverino, University Parthenope, Naples A study by Human Brain Project (HBP) researchers has identified a new marker for predicting the clinical outcome of patients with Amyotrophic Lateral Sclerosis (ALS) through magnetoencephalography. This marker can be measured in the brain during its resting...

Connectomic comparison to mouse revealed massively expanded interneuron-to-interneuron networks in human. Credit: Loomba, Helmstaedter, MPI for Brain Research The analysis of the human brain is a central goal of neuroscience. However, for methodological reasons, research has largely focused on model...

You used to be able to make snap judgments in your 20s, but now it feels like you take a lot longer to react to questions, decisions and challenges put before you. Don’t fret, it’s not that you’re losing brain power. Your response time does tend to slow down as you age, but a new study...
