Scientists might have found an early detection method for some forms of dementia, according to new research by the University of Arizona and the University of Toronto’s Baycrest Health Sciences Centre. According to the study published in the journal Neuropsychologia last month, patients with a rare neurodegenerative brain disorder called Primary Progressive Aphasia, or PPA,

Humans use imagination a lot, whether it be thinking about what’s for dinner later tonight or trying to imagine what someone else on the other side of the world may be experiencing after reading the news. As situations become farther away from reality and more distal, imagining a situation becomes more difficult. The limits to

A team of scientists at NeuroElectronics Research Flanders (NERF- empowered by imec, KU Leuven and VIB) found that highly demanding and rewarding experiences result in stronger memories. By studying navigation in rats, the researchers traced back the mechanism behind this selective memory enhancement to so-called replay processes in the hippocampus, the memory-processing center of the

Dietary lipids, already an important source of energy for tiny preemies, also provide a much-needed brain boost by significantly increasing global brain volume as well as increasing volume in regions involved in motor activities and memory, according to research presented during the Pediatric Academic Societies 2019 Annual Meeting. “Compared with macronutrients like carbohydrates and proteins,

A KAIST research team identified the intrinsic control architecture of brain networks. The control properties will contribute to providing a fundamental basis for the exogenous control of brain networks and, therefore, has broad implications in cognitive and clinical neuroscience. Although efficiency and robustness are often regarded as having a trade-off relationship, the human brain usually

Research suggests that having a happy spouse leads to a longer marriage, and now study results show that it’s associated with a longer life, too. The study was published in Psychological Science, a journal of the Association for Psychological Science. “The data show that spousal life satisfaction was associated with mortality, regardless of individuals’ socioeconomic

A specially designed computer program can help diagnose post-traumatic stress disorder (PTSD) in veterans by analyzing their voices, a new study finds. Published online April 22 in the journal Depression and Anxiety, the study found that an artificial intelligence tool can distinguish—with 89 percent accuracy—between the voices of those with or without PTSD. “Our findings

Young people with cognitive impairments and developmental disabilities, including Down syndrome, have similar weight-loss trajectories to those with typical cognitive function after bariatric surgery, according to a new study in Pediatrics authored by psychologists at Children’s National Health System. The study is the first to look at post-surgical outcomes for this subgroup of adolescent bariatric

Researchers at the University of Minnesota have developed a unique 3D-printed transparent skull implant for mice that provides an opportunity to watch activity of the entire brain surface in real time. The device allows fundamental brain research that could provide new insight for human brain conditions such as concussions, Alzheimer’s and Parkinson’s disease. The research

The next time you’re offered a free sample as you’re walking past a storefront, go ahead and take it. But be aware that the more you like that little chunk of cheese or sip of herbal tea, the likelier your brain’s internal map will warp in a way that increases your ability to return to

Seemingly harmless fluid-filled spaces around the cerebral small vessels, commonly seen on brain MRIs in older adults, are now thought to be associated with more compromised cognitive skills, according to a Vanderbilt University Medical Center study published in Neurology. The new findings challenge longstanding beliefs that these areas — known as perivascular spaces — are

Delusions are one of the most common symptoms of psychosis, but little is known about what causes them. A new study from researchers at Columbia University and New York State Psychiatric Institute offers insight into the development of delusions, which could lead to better treatments for people with psychosis. The findings were published in Brain.

Using strong and targeted but noninvasive magnets at specific sites in the brains of people with and without mild learning and memory problems, Johns Hopkins researchers report they were able to detect differences in the concentrations of brain chemicals that transmit messages between neurons. The strength of these magnetic fields allows the researchers to measure

New guidelines that reduce the amount of rest required for children recovering from a concussion have been developed by CanChild, a McMaster University research institute. “For children, recovering from a concussion is like a snakes and ladders game, as there are times where they may have rapid improvement and climb through the steps more quickly,

Columbia engineers and neuroscientists have joined forces to create 3D videos of individual nerve cells moving, stretching and switching on inside fruit fly larvae as they move. Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work together to help the body sense where it is in space. To accomplish this feat,

Experts from the Basque research centre BCBL have shown for the first time that the way in which the activity of two brains is connected depends on whether the dialogue takes place in the native language or in a foreign language. As two people speak, their brains begin to work simultaneously, synchronizing and establishing a

Researchers at Tokyo Institute of Technology, Imperial College London and the University of Tokyo have demonstrated that physical coordination is more beneficial in larger groups. The researchers used robotic interfaces to test coordination in groups of two, three and four partners, and found that performance was improving with every additional group member. The researchers believe

While many studies have found associations between greater levels of physical activity and lower rates of depression, a key question has remained — does physical activity actually reduce the risk of depression or does depression lead to reduced physical activity? Now a team led by Massachusetts General Hospital (MGH) investigators has used a novel research

More people today are poised to explore space than ever before; those who do will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, M.D., and co-author Lonnie G. Petersen, M.D.,Ph.D., University of California San Diego,

Mindfulness may be associated with fewer menopausal symptoms for women, according to a Mayo Clinic study recently published in Climacteric: The Journal of the International Menopause Society. Researchers discovered that being mindful may be especially helpful for menopausal women struggling with irritability, anxiety and depression. “In this study, we found that midlife women with higher
