Summary: New research from Yale demonstrates that predictive models connecting brain activity to behavior must generalize across diverse datasets to be clinically useful. By training models on varied neuroimaging datasets, the team showed that properly designed models can retain predictive accuracy even when applied to datasets with different demographic, geographic, and clinical profiles. This work … Read more

Summary: Improved glucose control can reverse or reduce brain changes and support cognitive function in young people with Type 1 diabetes. Source: Nemours Tight blood glucose control in teenagers with Type 1 diabetes appears to lessen the condition’s harmful effects on the developing brain, according to a study published today in Nature Communications. The trial … Read more

Summary: Engineers and clinicians have created a flexible, steerable microcatheter that lets neurosurgeons control the tip in any direction while navigating the brain’s intricate arteries and vessels. Source: UCSD A multidisciplinary team of engineers and physicians at the University of California San Diego has developed a soft, steerable microcatheter that gives neurosurgeons precise three-dimensional control … Read more

Summary: A new study investigates visual masking, an illusion in which a quickly presented second image prevents conscious perception of a first image, revealing how the brain constructs awareness. Researchers have now demonstrated this visual masking effect in mice and shown that it mirrors human perception, supporting the idea that similar neural processes underlie the … Read more

The eyes can reveal a great deal about attention. Whether you’re taking an exam or guiding a dog across a busy street, the capacity to ignore irrelevant sights and sounds—or to remain alert to potential threats—is essential for effective performance and safety. Recent research at Duke University used monkeys to explore how the brain handles … Read more

NIH-funded research offers new imaging hope for patients with limited treatment options Epilepsy can cause uncontrollable seizures that significantly reduce quality of life, limit everyday activities, and lead to social stigma and isolation. For many patients, standard antiepileptic medications control seizures effectively, but about one third of people with epilepsy do not respond to drug … Read more

Summary: A study examines how exposure to a major natural disaster may accelerate molecular signs of aging in the immune systems of rhesus macaques. Source: Arizona State University When Hurricane Maria struck Puerto Rico in September 2017 as a powerful category 4 storm, it caused historic destruction across the island. The immediate aftermath claimed thousands … Read more

Summary: Chronic stress can trigger or worsen mental health conditions like anxiety and depression and may accelerate biological aging. Researchers outline practical stress-management strategies that build resilience to stressors and may help protect cells from stress-related ageing. Source: The Conversation Moderate stress can support growth and performance, but excessive stress harms mental and physical wellbeing … Read more

Summary: Researchers have developed a high-resolution imaging workflow that enables visualization of several dozen proteins within a single thin tissue section using fluorescence microscopy. Using this approach, the team produced a detailed spatiotemporal map of human retinal organoid development, capturing how healthy retinal tissue forms over time and assembling a time series that spans the … Read more

Summary: Parental stress is higher among parents who themselves have sleep disorders and among parents whose children have sleep disorders. Source: PLOS New research published in PLOS ONE finds that parental stress is substantially higher when parents suffer from sleep disorders or when their children experience sleep problems. The study, led by Ray Merrill and … Read more
