A New Model Sheds Light on How We Learn Motor Skills

Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased ...

Muscle Biopsy Test for Biomarker Could Lead to Earlier Diagnosis of ALS

Amyotrophic lateral sclerosis (ALS) is a progressive disease of the nervous system. It affects nerve cells in the brain and spinal cord called motor neurons. Motor neurons control muscle movement and ...

Walking Gives the Brain a 'Step-Up' in Function for Some

It has long been thought that when walking is combined with a task -- both suffer. Researchers have now found that this is not always the case. Some young and healthy people improve performance on ...

Neuroscientists Create Maps of the Brain After Traumatic Brain Injury

Scientists have discovered that an injury to one part of the brain changes the connections between nerve cells across the entire ...

ADHD and ASD: What the Eyes Could Reveal

Researchers found that recordings from the retina could identify distinct signals for both attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), providing a potential ...

Understanding Learning by Inference

Both humans and other animals are good at learning by inference, using information we do have to figure out things we cannot observe directly. New research shows how our brains achieve this by ...

Scientists Unravel the Mystery of Genes That Are Key to Brain Development

New research shows the mechanism by which genes coding for a subset of long non-coding RNA (lncRNA) interact with neighboring genes to regulate the development and function of essential nerve ...

The Lasting Symptoms Among COVID-19 Long Haulers

More than two years after the COVID-19 pandemic erupted, scientists have become increasingly aware of a group of patients -- so-called 'long haulers' -- who remain plagued by a combination ...

How the Cerebellum Modulates Our Ability to Socialize

The cerebellum is essential for sensorimotor control but also contributes to higher cognitive functions including social behaviors. Researchers uncovered how dopamine in the cerebellum modulates ...

Gold Ribbon Not Necessary: Healthy Brain and Body Function Are the Rewards in This Game

Researchers have found that even the oldest adults can benefit from a game-like intervention that targets cognitive and physical function by combining body movement with tasks that stimulate frontal, ...

Preadolescents Exposed to High Levels of Air Pollution in Their First Years of Life Display Changes in Brain Connectivity

Higher exposure to air pollution is associated with higher functional brain connectivity among several brain regions in preadolescents, while exposure to traffic noise was not, according to a study. ...

Opioid Analgesic Fentanyl May Cause Autism-Like Behavior in Young Mice, Study Finds

A new study reveals that opioid analgesic fentanyl may induce autism-like behaviors in young male and female mice. The findings indicate that reduced expression of the gene Grin2b in the anterior ...

Brain Signal Irregularity May Provide Clues to Understanding Epileptic Process

Researchers propose a new method to differentiate signals from the epileptic focus from those recorded in other parts of the brain without the presence of an epileptic seizure. This technique may ...

Staring at Yourself During Virtual Chats May Worsen Your Mood

A new study finds that the more a person stares at themself while talking with a partner in an online chat, the more their mood degrades over the course of the conversation. Alcohol use appears to ...

Researchers Demonstrate Near-Non-Invasive In-Vivo Imaging in Mouse Cortex at an Unprecedented Depth

A research team has demonstrated in-vivo imaging of fine neuronal structures in mouse cortex through the intact skull at an unprecedented depth of 750 µm below pia, making high-resolution microscopy ...

Healthy Human Brains Are Hotter Than Previously Thought, Research Finds

New research has shown that normal human brain temperature varies much more than we thought, and this could be a sign of healthy brain function. The new study has produced the first 4D map of healthy ...

Neuroscientists Find New Factors Behind Better Vision

The size of our primary visual cortex and the amount of brain tissue we have dedicated to processing visual information at certain locations of visual space can predict how well we can see, a team of ...

Researchers Identify a Brain Circuit for Addiction Remission

In the United States, substance use disorders are a leading cause of death among young people. Treatments such as deep brain stimulation hold promise for helping people overcome addiction, but many ...

Brain Differences in Pain Modulation in People With Self-Injury Behavior

Researchers might have found an explanation for why people with self-injury behavior generally feel less pain than others. The key seems to be a more effective pain-modulation system, a discovery ...
