Animal Study Shows How Exercise May Energize Brain Cell Function
Johns Hopkins Medicine

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.

What Salamanders Can Teach Us About Baseball
University of Louisville

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.

Scientists Turn Tastes On and Off by Activating and Silencing Clusters of Brain Cells
Columbia University Irving Medical Center

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.

Male Hormone Testosterone Cause of Sex Differences in Parkinson’s Disease Risk, Study Suggests
American Physiological Society (APS)

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.

Modulating Brain’s Stress Circuitry Might Prevent Alzheimer’s Disease
UC San Diego Health

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.

Parkinson Drug May Prevent and Delay AMD
Research to Prevent Blindness

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.

New Brain Imaging Technique Identifies Previously Undetected Epileptic Seizure Sites
National Institute of Biomedical Imaging and Bioengineering

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.

Imitating Synapses of the Human Brain Could Lead to Smarter Electronics
American Chemical Society (ACS)

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.
