Us Versus Them: Harming the 'Outgroup' Is Linked to Elevated Activity in the Brain's Reward Circuitry

Humans tend to form groups, which often find themselves in conflict with rival groups. But why do people show such a ready tendency to harm people in ...

Stress Accelerates Immune Aging, Study Finds

Stress -- in the form of traumatic events, job strain, everyday stressors and discrimination -- accelerates aging of the immune system, potentially increasing a person's risk of cancer, ...

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 ...

How the Brain Controls Symptoms of Sickness

Researchers have discovered a small population of neurons near the base of the brain that can induce symptoms of sickness, including fever, appetite loss, and warm-seeking ...

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 ...

Cancer Survivors Grew to 18 Million in the US; More Than Two-Thirds Aged 65 Years or Older

A new report shows more than 18 million Americans (8.3 million males and 9.7 million females) with a history of cancer were living in the United States as of January 1, 2022, with a little over 12 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Learning and Remembering Movement

Researchers examining the brain at a single-neuron level found that computation happens not just in the interaction between neurons, but within each individual neuron. Each of these cells, it turns ...

'Good' Bacteria to Tackle Depression

Intestinal flora plays an important role in health -- including mental health. Researchers have shown that probiotics can support the effect of antidepressants and help to alleviate ...

Social Isolation Is Directly Associated With Later Dementia

Interdisciplinary study shows changes to brain structures associated with memory and cognitive function are directly linked to social isolation. The data shows that socially isolated people are 26% ...

Three Distinct Brain Circuits in the Thalamus Contribute to Parkinson's Symptoms

Neuroscientists identified three circuits in the thalamus that influence the development of motor and nonmotor symptoms of Parkinson's disease. And by manipulating these circuits, they could ...
