Dozens of molecules may tangle up with rogue bundles of tau, a protein that normally gives nerve fibers structure, to cause brain cell damage that contributes to neurodegenerative diseases, a new study shows. Neuroscientists have previously found that tau can become toxic when extra chemical molecules accumulate with its structure in the brain, causing it

A first-in-human study presented at the Society of Nuclear Medicine and Molecular Imaging 2020 Annual Meeting has demonstrated the safety, favorable pharmacokinetic and dosimetry profile of 64Cu-EBRGD, a new, relatively long-lived PET tracer, in patients with glioblastomas. The radiotracer proved to be a superior, high-contrast imaging diagnostic in patients, visualizing tumors that express low or

Science is collaborative by nature, since scientific knowledge only advances, step by step, through combined efforts and findings. Nevertheless, there is often a lack of communication regarding the more technical and everyday advances in laboratory work, and as a result, research progresses less quickly. In recent years, the development of the digital ecosystem has resulted

An innovative use of focused ultrasound being pioneered at the University of Virginia School of Medicine is showing promise against glioblastoma, the deadliest brain tumor, and could prove useful against other difficult-to-treat cancers. The technique hits cancer cells with a drug that sensitizes them to sound waves, then blasts them with focused ultrasound. The sound

Researchers at Beijing Normal university and Leiden University have recently carried out a study investigating patterns in neural activity that could be observed in humans during intergroup conflicts (i.e., conflicts between different groups of individuals). Their paper, published in Nature Neuroscience, draws inspiration from “The crowd: A study of the popular mind,” a book by

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. This is shown by a recent study by the University of Bonn. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer’s disease. However, the results suggest that such agents may

How much we value an item is often related to what other people have. You might want the newest fashion, but not once everybody has it. Or, winning a free lunch at your favorite restaurant might not seem as great if the other person won a million dollars. Now, researchers in Japan have discovered a

Each day, humans and animals rely on habits to complete routine tasks such as eating and sleeping. As new habits are formed, this enables us to do things automatically without thinking. As the brain starts to develop a new habit, in as little as a half a second, one region of the brain, the dorsolateral

The human-made chemicals that make our kitchen pans stick-free, our athletic wear water-repellent and firefighting chemicals more efficient do their jobs incredibly well, but it’s at the expense of lingering in the body and environment for what is believed to be forever. These forever chemicals, perfluorooctane sulfonate and perfluorooctanoic acid, more commonly known as PFOS

(HealthDay)—Many mothers-to-be feel overwhelmed by stress, and it might have implications for their babies’ brain development in the womb, a new study suggests. The researchers found that even in a group of highly educated, healthy pregnant women, stress and anxiety were common. More than one-quarter reported higher-than-average levels of “perceived stress,” while a similar number

Baby born with a tiny head and part of his BRAIN sticking out from his misshapen skull defies slim chance of survival to reach his first birthday Ozzie Gordon’s birth defect causes his brain and skull to form incorrectly  His brain bulged outside of his skull, which was later fixed with surgery  Parents Omobola and

Brain imaging may one day be used to help diagnose mental health disorders—including depression and anxiety—with greater accuracy, according to a new study conducted in a large sample of youth at the University of Pennsylvania and led by Antonia Kaczkurkin, Ph.D. and Theodore Satterthwaite, MD. And knowing more about the neurobiology behind psychiatric disorders could

Zika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. Employing different approaches to answer different questions, two research teams

English and Italian speakers with dementia-related language impairment experience distinct kinds of speech and reading difficulties based on features of their native languages, according to new research by scientists at the UC San Francisco Memory and Aging Center and colleagues at the Neuroimaging Research Unit and Neurology Unit at the San Raffaele Scientific Institute in

Scientists at Rutgers University-Newark have discovered that when a key protein needed to generate new brain cells during prenatal and early childhood development is missing, part of the brain goes haywire—causing an imbalance in its circuitry that can lead to long-term cognitive and movement behaviors characteristic of autism spectrum disorder. “During brain development, there is

The top number on a blood pressure test is widely viewed as the best gauge of a person’s overall risk for heart disease. But the bottom number could be important when it comes to evaluating the chance of a person having scars on their brain that could be an indicator for dementia, stroke or falls.

For boxers and mixed martial arts (MMA) fighters, is there a safe level of exposure to head trauma? A new study shows different effects in the brain for younger, current fighters compared to older, retired fighters. The study is published in the December 23, 2019, online issue of Neurology, the medical journal of the American

An article published in Proceedings of the National Academy of Sciences (PNAS) describes a new pathway in the central nervous system to expel waste substances from the brain through the creation of corpora amylacea (CA), aggregates formed by glucose polymers amassing waste products. The study, which opens new views on the clinical practice regarding neurodegenerative

The brain mechanism that enables us to maintain a constant body temperature may also be the key to rapid weight loss, a new study finds. In experiments involving mice that were given a calorie-restricted diet, scientists at Scripps Research discovered that blocking a brain receptor that normally regulates body heat resulted in significant weight reductions.

Researchers working in The N.1 Institute for Health at NUS, led by Assistant Professor Camilo Libedinsky from NUS Psychology, and Senior Lecturer Shih-Cheng Yen from the Innovation and Design Programme at NUS Engineering, have discovered that a population of neurons in the brain’s frontal lobe contain stable short-term memory information within dynamically-changing neural activity.
