Medical Xpress / How the brain filters out 'expected' sounds: Orbitofrontal cortex study offers new insight
Humans and other animals gradually learn what sounds or other sensory cues in their surroundings are meaningful or potentially threatening. Via a process known as habituation, they gradually learn to ignore non-threatening ...
Medical Xpress / How the brain can selectively focus attention on one voice among others in a noisy environment
MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the "cocktail party problem."
Medical Xpress / Lost under stress? Study shows cortisol can scramble the brain's internal map
The stress hormone cortisol disrupts the brain's navigational system. It impairs the function of the grid cells that play a crucial role in orientation. This has been verified by researchers from Ruhr University Bochum, Germany, ...
Medical Xpress / Experimental Alzheimer's drug reverses memory loss in mice by reprogramming gene activity
A team from the University of Barcelona has designed and validated in animal models an innovative compound with a pioneering mechanism of action for the treatment of Alzheimer's disease. Unlike current drugs, which mainly ...
Medical Xpress / How vitamin B2 could pave the way to new cancer therapies
The human body cannot produce vitamin B2—also known as riboflavin—itself; it must absorb the important substance through diet. The vitamin can be found in dairy products, eggs, meat and green vegetables. The metabolism ...
Medical Xpress / Research reveals how blood flow directs vessel health at the molecular level
How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi University and the InFLAMES ...
Medical Xpress / Multi-cytokine scaffold helps CAR-T cells fight cancer and HIV for longer
A research team led by Albert Einstein College of Medicine scientists has developed a new strategy to engineer immune cells that dramatically prolongs their effectiveness after being infused into patients to fight cancer ...
Medical Xpress / Targeting two flu proteins sharply reduces airborne spread, study finds
A long-running debate in vaccine design revolves around whether a vaccine should be optimized to prevent the virus from replicating inside an infected host or prevent the virus from transmitting to others. New research led ...
Medical Xpress / A new triple negative breast cancer target: Why HORMAD1 could guide treatment choices
A gene that is typically active only in reproductive cells may hold the key to new treatments for triple negative breast cancer, according to new research published in the journal Nature Communications. Scientists from the ...
Medical Xpress / The ghosts we see: Afterimages provide clues to how our brains perceive a stable environment
Our eyes alone do not provide us with a continuous and stable view of the world. They jump several times each second in rapid movements called saccades. Because the eye projects the world onto the retina, we should see the ...
Medical Xpress / Heat boosts antibiotics' effectiveness against prosthetic infections
Heat generated by alternating magnetic fields (AMF) helps common antibiotics work better against prosthetic joint infections, researchers at UT Southwestern Medical Center found. The study, published in Scientific Reports, ...
Medical Xpress / Novel compounds open new research avenues for Alzheimer's disease therapeutics
Alzheimer's disease is the most common cause of dementia, and it affects over 7 million people in the United States alone. Although there are treatments that can slow its progression, most of them treat its symptoms only ...
