Scientists have identified two chemical scents in the urine of female mice that arouse sexual behavior in males, a discovery that shines a spotlight on how mouse pheromones control behavior. The research, at Washington University School of Medicine in St. Louis, is available online in the journal Cell.
RPB-supported researchers have made a significant discovery that might lead to the delay or prevention of the most common cause of blindness in the elderly: age-related macular degeneration (AMD). Patients who take the drug L-DOPA (for Parkinson Disease, Restless Legs or other movement disorders) are significantly less likely to develop AMD and, if they do, it is at a significantly later age.
Researchers have developed a brain imaging technique for patients whose epilepsy does not respond to drug treatment and are not candidates for seizure-relieving surgeries. The imaging technique, known as glutamate chemical exchange saturation transfer (GluCEST), images changes in glutamate levels in brain structures that identify the location of seizures not detected with conventional MRI.
Researchers from the University of Houston have analyzed brain activity data collected from more than 400 people who viewed an exhibit at the Menil Collection, offering evidence that useable brain data can be collected outside of a controlled laboratory setting. They also reported the first real-world demonstration of what happens in the brain as people observe artwork.
Brain scans of people in a coma may help predict who will regain consciousness, according to a study published in the November 11, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study looked at connections between areas of the brain that play a role in regulating consciousness.
A new study by Berkeley Lab scientists has identified genetic factors that influence motor performance and body weight in a genetically diverse group of mice. The researchers also found the genes identified in the mice overlap significantly with genes related to neurological disorders and obesity in people.
Making a computer that learns and remembers like a human brain is a daunting challenge. The complex organ has 86 billion neurons and trillions of connections — or synapses — that can grow stronger or weaker over time. But now scientists report in ACS' journal Nano Letters the development of a first-of-its-kind synthetic synapse that mimics the plasticity of the real thing, bringing us one step closer to human-like artificial intelligence.
Organized extracurricular sport activities for children help them develop and improve cognitive skills, such as greater concentration capacity, that can in term greatly help them in the classroom, says Université de Montréal professor Linda Pagani.
Scientists at Wake Forest Baptist Medical Center have found new evidence that mindfulness meditation reduces pain more effectively than placebo.
More than five million Americans and 15 million caregivers are impacted by Alzheimer's disease. A leading neuroscientist at Florida Atlantic University has developed eight myths and truths about this prevalent form of dementia.
“Blink and you’ll miss it” isn’t only for eyelids. The human brain also blinks, dropping a few frames of visual information here and there. Those lapses of attention come fast — maybe just once every tenth of a second. But some people may be missing more than others, according to psychologists at the University of Wisconsin–Madison.
Principal Investigator Takes Questions and Demonstrates Procedure with Video and Animation via Virtual Press Conference Tuesday, November 10th at 1:00 p.m. ET
Some nerve cells in the inner ear can signal tissue damage in a way similar to pain-sensing nerve cells in the body, according to new research from Johns Hopkins. If the finding, discovered in rats, is confirmed in humans, it may lead to new insights into hyperacusis, an increased sensitivity to loud noises that can lead to severe and long-lasting ear pain.
Scientists at the University of North Carolina School of Medicine (UNC) and University of California, San Francisco (UCSF) have created a general tool to probe the activity of these orphan receptors, illuminating their roles in behavior and making them accessible for drug discovery
A UA researcher has provided the strongest evidence yet that it's possible for brains to fossilize and, in fact, a set of 520-million-year-old arthropod brains have done just that.
The thickness of the cortex in a region of the brain that specializes in facial recognition can predict an individual's ability to recognize faces and other objects.
Scientists at the University of North Carolina and UC-San Francisco created a general tool to probe the activity of orphan receptors, illuminating their roles in behavior and making them accessible for drug discovery for the first time.
The blood-brain barrier has been non-invasively opened in a patient for the first time. A team at Sunnybrook Health Sciences Centre in Toronto used focused ultrasound to enable temporary and targeted opening of the blood-brain barrier (BBB), allowing the more effective delivery of chemotherapy into a patient’s malignant brain tumor.
When it comes to preventing stroke, millions of Americans with irregular heartbeats face a choice: Take one of the powerful but pricey new pills they see advertised on TV, or a much cheaper 60-year-old drug can be a hassle to take, and doesn’t prevent stroke as well. It doesn’t seem like much of a contest -- until you do the math.
When peripheral nerves are damaged and their vital synaptic paths are disrupted, they have the ability to regenerate and reestablish lost connections. Using zebrafish, which are transparent at larval stages, the researchers identified key components that allows the nervous system to heal itself and literally obtain a whole new window into how axons regenerate.
