“Eat-Me” Signal Discovered in Synaptic Pruning and Maturation of New Neurons in the Adult Brain
The synaptic pruning of newborn neurons by microglia depends on phosphatidylserine in the adult brain. This mechanism is essential for the maturation of newborn neurons….
Alzheimer’s Disease: Protective Immune Cells Active Decades Before Symptom Onset
Boosting the brain’s defenses could help combat the disease. In individuals with a genetic predisposition to Alzheimer’s disease, the immune cells of the brain –…
Most Brain Studies Have Too Few Participants To Yield Reliable Findings
Findings will encourage more data sharing, collaboration among researchers. As brain scans have become more detailed and informative in recent decades, neuroimaging has seemed to…
Bacteria in the Nose Can Sneak Into the Brain – May Increase Risk of Alzheimer’s Disease
New research from Griffith University has shown that a bacterium commonly present in the nose can sneak into the brain and set off a cascade…
Nerve Repair “Glue” – Molecule Identified for Regulating the Repair of Injured Nerves
Researchers at The University of Queensland have identified a molecule essential for regulating the repair of injured nerves, which could help people recover from nerve…
Advanced Technology Highlights Connections Between Addictive Drugs and Brain Function
Researchers use advanced technology and mice to study dopamine neuron structure, addiction and the brain’s ability to recover. A late 1980s commercial meant to combat…
Even Mild COVID Can Cause Brain Shrinkage and Disrupt Mental Function
Most of what we know about how COVID can affect the brain has come from studies of severe infection. In people with severe COVID, inflammatory…
Skin Cancer Cells Sabotage Brain’s Immune Defenses With Alzheimer’s Protein
Amyloid beta, a protein known to build-up in the brains of Alzheimer’s patients, also helps skin cancer cells thrive when they spread to the brain,…
Objection: No One Can Understand What You’re Saying – Why Legal Documents Are Often So Impenetrable
An MIT study identifies ways that lawyers could make their written documents easier for the average person to read. Legal documents, such as contracts or…
Damage to General Intelligence Brain Networks Causes Dementia Patients To Struggle With Change
People with dementia struggle to adapt to changes in their environment because of damage to areas of the brain known as ‘multiple demand networks’, highly-evolved…
MIT’s New MRI Probe Can Reveal More of the Brain’s Inner Workings
Tracing connections between neuron populations could help researchers map brain circuits that underlie behavior and perception. Using a novel probe for functional magnetic resonance imaging…
Game-Changing Digital Toolbox May Help Diagnose Dementia Earlier
Detection of subtle differences in cognitive behaviors may help delay, prevent the onset. Detecting cognitive changes early in the onset of dementia would be a…
Researchers Discover How the Human Brain Separates, Stores, and Retrieves Memories
NIH-funded study identifies brain cells that form boundaries between discrete events. Researchers have identified two types of cells in our brains that are involved in…
A Protein That Is Too Effective: The Role of Lipids in the Development of Alzheimer’s Disease
A European consortium coordinated by UNIGE shows how a mutation in the APOE protein changes the lipid transport in the brain and could promote the…
Natural Mineral May Reverse Memory Loss and Boost Learning
Selenium – a mineral found in many foods – could reverse the cognitive impact of stroke and boost learning and memory in aging brains, according…
Making the Invisible Visible: A Clearer “Picture” of Blood Vessels in Health and Disease
Johns Hopkins Medicine researchers have developed and tested a new imaging approach they say will accelerate imaging-based research in the lab by allowing investigators to…
More Alcohol, Less Brain: Association Begins With an Average of Just One Drink a Day
The research, using a dataset of more than 36,000 adults, revealed that going from one to two drinks a day was linked with changes in…
