Five Distinct Patterns of Brain Aging Uncovered by 50,000 Scans

Medicine, Neuroscience, Science /

A comprehensive analysis of nearly 50,000 brain scans has identified five unique patterns of brain atrophy linked to aging and neurodegenerative diseases. The study also connected these patterns to lifestyle factors such as smoking and alcohol consumption, as well as to genetic and blood markers related to health and disease risk. Andrei Irimia, a gerontologist […]

Scientists Identify Key Brain Network for Creativity

Neuroscience, Science /

Neuroscientists believe they have pinpointed the extensive neural network that fuels the brain’s creativity. Unlike specific movements or sensory responses, creative thinking is not limited to a single area of the brain’s outer cortex. However, researchers from Baylor College of Medicine have identified the brain circuits crucial to certain types of creative thought. When nine

Serotonin Affects How People Learn From and React to Negativity

Neuroscience, Science /

According to a new study in Nature Communications, increasing serotonin can alter how people learn from negative information and enhance their response to it. Researchers from the University of Oxford’s Department of Psychiatry and the National Institute of Health and Care Research (NIHR) Oxford Health Biomedical Research Center (OH BRC) discovered that increasing serotonin levels

New Compound Restores Memory Function in Alzheimer’s Cases

Healthcare, Neuroscience, Science /

Instead of focusing on fighting the plaques associated with Alzheimer’s, researchers decided to explore the possibility of increasing electrical oscillations in the brain. They created a molecule that successfully achieved this in mice, offering hope for a new treatment approach in humans. Rethinking the Role of Brain Plaques in Alzheimer’s Disease It’s increasingly clear that

Research Identifies the Brain’s Source of Creativity

Neuroscience, Science /

Have you ever experienced a sudden breakthrough on a tough problem while thinking about something entirely different? This kind of creative thought, a defining trait of humanity, often appears unexpectedly, almost paradoxically, when least sought. Unveiling the Origins of Creativity The neurological origins of creativity—how our brains generate these out-of-the-box ideas—have been equally elusive. However,

Many of Us Are Dominantly Right-Handed but Left-Eyed. Here’s the Reason

Biology, Neuroscience, Psychology /

The study explores the complex interplay of handedness and visual biases in humans, drawing parallels with similar traits observed across the animal kingdom. While handedness is well-known as a defining characteristic, the study reveals lesser-known biases that impact social dynamics and cognitive functions. Human Biases and Brain Lateralization Humans exhibit a strong tendency towards right-handedness,

Scientists Discover Brain Vascular Changes Associated with Alzheimer’s Disease

Neuroscience, Science /

The blood-brain barrier (BBB)—a network of blood vessels and tissues that protects the brain from harmful substances in the blood—is disrupted in Alzheimer’s disease. Researchers at the Mayo Clinic and collaborators have now identified unique molecular signatures of BBB dysfunction, potentially leading to new diagnostic and treatment methods. Discovery and Analysis of Molecular Signatures “These
