Cognitive impairment affects 30%â80% of patients with heart failure, yet the mechanisms beyond reduced brain blood flow remain poorly defined. Here we show that circulating factors released during heart failure trigger…
Perceptual judgements and their metacognitive evaluation are considered tightly coupled aspects of decision-making, yet emerging evidence suggests distinct neural mechanisms underlie these processes. In motion…
Nepal, Aug. 14 -- Last Spring, I was in Sydney, Australia, working on my research project and carrying my dream of permanently residing in the country. After decades of professional research and ...
More than a decade ago, Dr. Matthew Hebb was treating patients with Parkinson's disease using deep brain stimulation by implanting tiny electrodes into the brain and delivering electrical signals to control tremors. He…
With temperatures forecast to reach around 37°C (99°F) in places, reaching for an ice cream or an icy drink might seem like an excellent idea. There is, however, one small hazard to eating your frozen treat with too much…
Obesity is a global health concern that can contribute to diabetes, cardiovascular disease and other metabolic disorders. While many health conditions can lead to obesity, an increasingly worrying cause is found on…
Consumers are increasingly choosing products from companies that demonstrate genuine environmental responsibility. While many studies have linked environmental, social and governance (ESG) performance with stronger…
A new study, led by researchers at the University of Staffordshire, has found evidence of potentially hazardous microbial growth on mummified human and animal remains advertised for sale online—posing risks to both…
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common…
A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that…
Traumatic brain injury (TBI) in Pakistan is associated with a high risk of death and disability long after the initial injury, even in mild to moderate cases, according to two new studies in JAMA Network Open led by…
How do we remember the distant past? For decades, scientists have believed synaptic potentiation—the adaptive strengthening of our brain's cellular connections—to be the key to memory retention. Researchers from the…
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it. On the one hand, it has to be open to whatever new sensory information may come its…
During a reading lesson, Mateo, an elementary multilingual learner (MLL) in a Delaware public school, read "sit" as "seat." Jon Kittle, his reading interventionist, walked him through the short vowel sound, but Mateo…
Millions of investors using the Robinhood app tend to favor simpler, easy-to-understand stocks, according to new research from Washington State University—and those stocks outperformed more complex firms during the study…
Blood biomarkers may make it possible to detect changes seen in Alzheimer's disease without advanced brain imaging or cerebrospinal fluid tests. At the same time, much of the research behind today's biomarkers has been…
Watchdog science journalism has become a fundamental tool to counter scientific malpractice, such as publication fraud, abuse and political and corporate manipulation of science. A study by the Universitat Autònoma de…
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron…
Most neuroscience research still runs on mice, even though much of what applies to mice does not hold up in humans. Marmosets have emerged as a bridge between species. However, comparing the brains of mice and marmosets…
Women on regimens of estrogen-only menopausal hormone therapy are at reduced risk of Alzheimer's disease, a study by Stanford Medicine investigators has found. Because estrogen-only therapy is generally prescribed for…
Overall, star employees tend to create value in different ways as their careers progress. Early on, they create outsized value through their individual performance. Experienced stars, meanwhile, contribute by helping…
Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed an automated system that uses MRI to measure brain tissue changes in…
A protein inside appetite-controlling brain cells may play an important role in preventing overeating and obesity, particularly when high-fat foods are readily available. Unexpected differences between males and females…
Over 57 million people worldwide live with dementia, causing 36.3 million disability-adjusted life years (DALYs) and ranking as ...
The language network in your brain can be seen, even if you aren't saying a word. For a study published in Nature Communications, researchers used data from more than 1,900 functional magnetic resonance imaging (fMRI)…
Migraine is a highly prevalent disabling disorder affecting approximately 1 billion people worldwide.1 Its pathophysiology involves activation and sensitisation of the trigeminovascular system, resulting in the release…
Motion sickness is provoked when ambiguity or ‘conflict’ within vestibular signals or within visual-vestibular interactions challenge the constancy of ‘uprightness’ and the interpretation of self-motion versus…
Background Long-term functional and vocational outcomes after traumatic brain injury (TBI) remain difficult to predict, limiting prognostic counselling and rehabilitation planning. We aimed to evaluate the…
Background Repetitive head impacts in former contact sport athletes are associated with cognitive impairment, accelerated cerebral atrophy and risk of neurodegenerative disease. Epigenetic clocks derived from…
Background Psychiatric comorbidities are increasingly recognised in demyelinating diseases, yet their frequency and timing in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are not well defined…
