by Ingrid Fadelli , Medical Xpress Credit: Hansen et al. Recent technological advances are allowing neuroscientists to map the human brain with increasing precision, highlighting connections between different regions and their function in greater depth. While the role of many brain regions has been broadly identified, the unique contribution of the brainstem to their function...

Global effort to map the human brain releases first data
October 1, 2024 by Allen Institute for Brain Science The BRAIN Initiative Cell Atlas Network (BICAN) has launched its first major data release, marking a significant milestone in the ambitious effort to map the whole human brain. The data, accessible through the BICAN Rapid Release Inventory, includes single-cell and single-nucleus transcriptomic and epigenomic profiles from...

Scientists Mapped The Human Brain’s Sewage System For The First Time
MRI scans of brains with red arrowsCSF pathways in the brain. (Yamamato et al., PNAS, 2024)The inner workings of our brain’s ‘sewage system’ are finally coming to light after years of speculation. Deep within the crevices of five human brains, scientists have, for the very first time, imaged the dynamic intricacies of a underlying plumbing...

Researchers map how measles virus spreads in human brain
by Mayo Clinic Illustration of the virus which causes measles. Credit: CDC/ Allison M. 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...

Scientists built the largest-ever map of the human brain. Here’s what they found
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...

Stem cell model of human brain development suggests embryonic origins of Alzheimer’s disease
INTERNATIONAL SOCIETY FOR STEM CELL RESEARCH IMAGE: HUMAN 3D CORTICAL SPHEROID WITH A PSEN1 MUTATION. CREDIT: ERIN HURLEY, UNIVERSITY OF TEXAS AT SAN ANTONIO Alzheimer’s disease (AD) mainly affects the older population. 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...

Rare electrical recordings from within the human brain give new picture of neural activity
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...

Human Brain Project researchers identify new marker of ALS outcome
by Roberto Inchingolo, Human Brain Project Equipment used in the study. 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...
