Study Helps Explain Why Motivation to Learn Declines With Age

Neuroscientists have identified a brain circuit critical for learning to make decisions that require evaluating the cost or reward of an action. They showed this circuit is negatively affected by ...

How Genetic Variation Gives Rise to Differences in Mathematical Ability

DNA variation in a gene called ROBO1 is associated with early anatomical differences in a brain region that plays a key role in quantity representation, potentially explaining how genetic variability ...

Happiness and the Evolution of Brain Size

Serotonin can act as a growth factor for the stem cells in the fetal human brain that determine brain ...

'Spooky' Similarity in How Brains and Computers See

The brain detects 3D shape fragments (bumps, hollows, shafts, spheres) in the beginning stages of object vision - a newly discovered strategy of natural intelligence that researchers also found in ...

Neuron-Based Gene Expression Study Reveals Insights on Fear and Its Regulation

The expression of a gene called CREB in certain neurons may function as a switch to regulate feelings of fear and its ...

Single Brain Region Links Depression and Anxiety, Heart Disease, and Treatment Sensitivity

Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully ...

COVID-19 Infection May Be Part of a 'Perfect Storm' for Parkinson's Disease

Can COVID-19 infection increase the risk of developing Parkinson's disease? That's the question posed by a new commentary that explores three known case studies of people developing ...

Researchers Identify How Night-Shift Work Causes Internal Clock Confusion

Night-shift workers face an increased risk of obesity and diabetes, but the underlying reason for that has been a mystery. Now, researchers have found a potential cause for metabolic changes during ...

Immune Response the Probable Underlying Cause of Neural Damage in COVID-19

A new study shows that it is probably the immune response to, rather than the virus in itself, that causes sudden confusion and other symptoms from the nervous system in some patients with ...

Multiple Sclerosis as the Flip Side of Immune Fitness

About half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study has now shown how this genetic predisposition contributes to the development of the autoimmune disease ...

Bacterial Metabolism of Dietary Soy May Lower Risk Factor for Dementia

A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia - with the help of the right bacteria, according to a new ...

Gut Hormone Blocks Brain Cell Formation and Is Linked to Parkinson's Dementia

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a research team has discovered. It could help pave the way for new drugs to treat dementia in patients with ...

Highly Effective Tumor Detection Strategy for Common Childhood Brain Tumors

A team of scientists have developed a way to more accurately both detect and monitor a common type of pediatric brain cancer, setting the stage for giving clinicians a real-time view into how the ...

Tumor DNA in Spinal Fluid Could Help Doctors Better Monitor Childhood Brain Cancer

Researchers have demonstrated that a new liquid biopsy approach overcomes traditional barriers to quickly and efficiently diagnose and monitor high-grade pediatric ...

New Research Reveals Why Low Oxygen Damages the Brain

Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a newly published ...

Scientists Take Major Step Toward Angelman Syndrome Gene Therapy

Babies born with a faulty maternal copy of the UBE3A gene will develop Angelman syndrome, a severe neurodevelopmental disorder with no cure and limited treatments. Now, for the first time, scientists ...

Diagnosing Parkinson's Disease With Skin Samples Could Lead to Earlier Detection

New research shows a simple skin test can accurately identify Parkinson's disease, which could lead to earlier detection of the disease and better outcomes for patients. Currently, ...

Cognitive Performance Better Than Our Predecessors

We employ our cognitive skills daily to assimilate and process information. A new empirical study shows that we do better at this task than those born a century ago. But cognitive capacity still ...

Hypothyroidism in Pregnant Mothers Linked to ADHD in Their Children

Low levels of key, body-regulating chemicals in mothers during the first three months of pregnancy may interfere with the baby's brain development, a large study ...

Phase 3 Clinical Trial to Treat Mild Alzheimer's Disease Using Deep Brain Stimulation

Medical researchers are enrolling individuals in an international phase 3 clinical trial to examine the safety and effectiveness of deep brain stimulation to treat Alzheimer's. The study uses ...

Researchers have linked a brain region to what they call neural polarization, offering a glimpse into the partisan brain in the weeks leading up to what is arguably the most consequential U.S. ...

New Anti-AB Vaccine Could Help Halt Alzheimer's Progression, Preclinical Study Finds

A preclinical study by neuroscientists indicates that an antigen-presenting dendritic vaccine with a specific antibody response to oligomeric A-beta may be safer and offer clinical benefit in ...
