Summary: Scene-selective cortical regions show greater age-related sensitivity than face-selective regions in both perception and memory. Source: UT Dallas Healthy brains generally become less efficient with age, but this decline is neither uniform across tasks nor across brain regions. Mapping these differences helps clarify how the brain supports perception and memory throughout life. Researchers at … Read more

Summary: Decoding brain activity can advance brain–computer interfaces, improving treatments and enabling people with neurological conditions to interact more effectively with their environment. Source: Stanford. For more than a century, people have imagined linking the human brain—remarkably adaptable but vulnerable—to precise, reliable machines. Early science fiction speculated on clockwork enhancements and transplanted brains piloting starships. … Read more

Summary: A synthesized small-molecule drug that crosses the blood-brain barrier blocks the TGF‑β receptor in astrocytes. In aged mice this treatment reduced receptor activity to levels seen in younger animals, decreased neuroinflammation, and restored learning and spatial navigation abilities. Source: UC Berkeley Drugs that reduce brain inflammation may slow or reverse age-related cognitive decline Researchers … Read more

New research from the University of Florida suggests that producing new nerve cells in the hippocampus may help prevent memory loss and support memory improvement as people age or experience neurological challenges. Scientists find link in humans between nerve cell production and memory A study led by researchers at the University of Florida reports a … Read more

Have you ever wondered why some people find it easier to quit smoking than others? Recent research suggests that genetic differences that determine how quickly the body breaks down nicotine play a major role in that variation. Researchers at the Montreal Neurological Institute and Hospital – The Neuro, McGill University, report that individuals who metabolize … Read more

Image via Wikipedia Recent neuroscience research indicates that functional magnetic resonance imaging (fMRI) can reveal decision tendencies that people themselves do not fully predict. In experiments with students, patterns of brain activity recorded by fMRI sometimes forecasted which choice a person was more likely to make, even when the student’s conscious expectation about their own … Read more

Summary: New research from Brigham Young University reports that stress alters the gut microbiota of female mice in a way that mimics the effects of a high-fat diet. Source: Brigham Young University Stress may affect the gut as much as a poor diet, according to a new animal study. A team led by Laura Bridgewater, … Read more

Summary: Islets of Langerhans from mice overnourished during infancy displayed DNA methylation patterns normally seen in much older animals. Source: Baylor College of Medicine Researchers at Baylor College of Medicine report a mechanism that helps explain how overnutrition in early life can cause long-term metabolic problems such as diabetes. Published in the journal Environmental Epigenetics, … Read more

Summary: A new artificial intelligence convolutional neural network achieves 94.6% accuracy for near real‑time intraoperative diagnosis of brain tumors. Source: NYU Langone Health A new technique that combines advanced optical imaging with a deep learning algorithm enables accurate, near real‑time intraoperative diagnosis of brain tumors, a study finds. Published in Nature Medicine, the study compared … Read more

Summary: Researchers have produced a high-quality, chromosome-level reference genome for the common octopus, revealing about 2.8 billion base pairs organized across 30 chromosomes. This achievement comes from extensive, computer-assisted genome assembly and comparative analyses with other cephalopods. This reference sequence opens new avenues for understanding octopus biology, from neural organization and behavior to development and … Read more
