As we age or develop neurodegenerative diseases such as Alzheimer's, our brain cells may not produce sufficient energy to remain fully functional. Researchers discovered that an enzyme called SIRT3 that is located in mitochondria — the cell's powerhouse — may protect mice brains against the kinds of stresses believed to contribute to energy loss. Furthermore, mice that ran on a wheel increased their levels of this protective enzyme.

In a new study that could have implications for future drug discovery efforts for a number of neurodegenerative diseases, scientists from the Florida campus of The Scripps Research Institute (TSRI) have found that the interaction between a pair of brain proteins has a substantial and previously unrecognized effect on memory formation.

University of Georgia researchers have developed a simple technique to measure an individual’s visual processing speed—the speed at which an individual can comprehend visual information—in order to identify whether or not they may have cognitive issues.

University of Louisville researcher Bart Borghuis, Ph.D., has increased our understanding of how people and animals deal with sensorimotor delay in day-to-day interactions by analyzing the hunting skills of salamanders. His article, “The Role of Motion Extrapolation in Amphibian Prey Capture,” is published in today’s issue of The Journal of Neuroscience.

Most people probably think that we perceive the five basic tastes—sweet, sour, salty, bitter and umami (savory)—with our tongue, which then sends signals to our brain “telling” us what we’ve tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain.

Men are twice as likely as women to develop Parkinson’s disease. New research suggests that testosterone enhances the susceptibility of brain cells that control movement to damage from chemical imbalances, explaining the sex differences in the occurrence of Parkinson’s.

A new study done by University of Texas at Dallas researchers indicates that watching 3-D images of tongue movements can help individuals learn speech sounds. Researchers say the findings could be especially helpful for stroke patients seeking to improve their speech articulation.

In a novel animal study design that mimicked human clinical trials, researchers at University of California, San Diego School of Medicine report that long-term treatment using a small molecule drug that reduces activity of the brain’s stress circuitry significantly reduces Alzheimer’s disease (AD) neuropathology and prevents onset of cognitive impairment in a mouse model of the neurodegenerative condition. The findings are described in the current online issue of the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.

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.
