Brain inflammation caused by chronic nerve pain alters activity in regions that regulate mood and motivation, suggesting for the first time that a direct biophysical link exists between long-term pain and the depression, anxiety and substance abuse seen in more than half of these patients, UC Irvine and UCLA researchers report.
Brain lesions in children can be especially challenging to diagnose, according to a report in the journal Frontiers in Neurology by a multidisciplinary team of Loyola University Medical Center physicians.
Using functional magnetic resonance imaging, a team of UCLA researchers has shown for the first time that children with autism spectrum disorder (ASD) who are overly sensitive to sensory stimuli have brains that react differently than those with the disorder who don’t respond so severely to noises, visual stimulation and physical contact.

The witness on the stand says he saw the accused at the scene of the crime. Is he sure? How sure? The jury’s verdict could hinge on that level of certainty. Many decisions we make every day are influenced by our memories and the confidence we have in them. But very little is known about how we decide whether we can trust a memory or not. Cedars-Sinai researchers have identified a unique set of neurons in the medial temporal lobe, an area of the brain where memories and memory-based decisions are processed. They show that the activity of these neurons is indicative of the confidence by which a memory will be retrieved.

The ability to delay gratification in chimpanzees is linked to how specific structures of the brain are connected and communicate with each other, according to researchers at Georgia State University and Kennesaw State University.
After a concussion, a person can have disturbed sleep, memory deficits and other problems for years, but a new study suggests that despite these, sleep still helps them to overcome memory deficits, and the benefit is equal to that seen in individuals with no history of mild traumatic brain injury.
This conclusion is based on a new study conducted on rats at the University of Haifa. Prof. Mouna Maroun, the researcher leader, explains that given the similarity between the mechanisms in rats and humans responsible for coping with stress, “the immediate significance is that we cannot go on treating children affected by stress in the same way and with the same drugs that we use for adult patients”

– Individuals with a higher level of moral reasoning skills showed increased gray matter in the areas of the brain implicated in complex social behavior, decision making, and conflict processing as compared to subjects at a lower level of moral reasoning, according to new research from the Perelman School of Medicine and the Wharton School of the University of Pennsylvania in collaboration with a researcher from Charité Universitätsmediz in Berlin, Germany. The team studied students in the Masters of Business Administration (MBA) program at the Wharton School. The work is published in the June 3rd edition of the journal PLOS ONE.
A team of New York University neuroscientists has determined how a pair of growth factor molecules contributes to long-term memory formation.
Scientists at Duke Medicine have produced a 3-D map of the human brain stem at an unprecedented level of detail using MRI technology. In a study to be published June 3 in Human Brain Mapping, the researchers unveil an ultra high-resolution brain stem model that could better guide brain surgeons treating conditions such as tremors and Parkinson’s disease with deep brain stimulation (DBS).
An international team of scientists led by Cardiff University researchers has provided the strongest evidence yet of what causes schizophrenia - a condition that affects around 1% of the global population.
After reviewing outcomes from thousands of cases, researchers at Johns Hopkins report that patients with blocked neck arteries who undergo carotid stenting to prop open the narrowed blood vessels fare decidedly worse if their surgeons re-inflate a tiny balloon in the vessel after the mesh stent is in place.
You might not need to remember those complicated e-mail and bank account passwords for much longer. According to a new study, the way your brain responds to certain words could be used to replace passwords.
Though people can distinguish among millions of colors, we have trouble remembering specific shades because our brains tend to store what we’ve seen as one of just a few basic hues.
Sojourner Center, one of the largest and longest running domestic violence shelters in the United States, announced plans to develop the first world-class program dedicated to the analysis and treatment of traumatic brain injury (TBI) in women and children living with domestic violence, a largely unrecognized public health issue.
Researchers examined neuroimaging studies obtained in children and adolescents with sports-related concussions and found that the images appeared normal in 78% of cases. Although usually nondiagnostic, occasionally such studies can be useful in guiding decisions about return to play.
Researchers from the Canada North Concussion Network in Manitoba investigated the frequency of vestibulo-ocular dysfunction in children and adolescents with sports-related concussion and found that its presence was predictive of a prolonged recovery.

Much like the automatic focus of a camera, our eyes and brains must constantly recalibrate so that we can get a clear view of the changing—and always moving—world around us. Two studies funded by the National Eye Institute (NEI) show how the circuitry for this eye-brain coordination is assembled during early embryonic development.
Lightly stimulating the brain with electricity may improve short-term memory in people with schizophrenia, according to a new study by researchers at the Johns Hopkins University School of Medicine.

The study is published in the May 27, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Participants went through MRIs, which showed their brain activity when they viewed campaign ads on cage-free eggs.
Researchers at UAB have identified a chemical pathway that may be associated with seizures and shorter patient survival in some patients with malignant glioma, the most common and deadly form of brain tumor. The researchers suggest that a transporter known as SXC is responsible for boosting levels of glutamate in the brains of some glioma patients.
Picture yourself in a medical office, anxiously awaiting your annual flu shot. The nurse casually states, “This won’t hurt a bit.” But when the needle pierces your skin it hurts, and it hurts a lot. Your expectations have been violated, and not in a good way.

Certain proteins may slow the devastating memory loss caused by Alzheimer’s disease, according to a groundbreaking Iowa State University study.
Stem cell scientists at McMaster can now directly convert adult human blood cells to both central nervous system (brain and spinal cord) neurons as well as neurons in the peripheral nervous system (rest of the body) that are responsible for pain, temperature and itch perception. This means that how a person’s nervous system cells react and respond to stimuli, can be determined from his blood.
A simple blood test developed at UNT Health Science Center to detect early Alzheimer's disease is a step closer to being used to screen older adults.
