UCLA helps many to live long and prosper
In Westwood, more than 100 faculty experts from 25 departments have embarked on anall-encompassing push to cut the health and economic impacts of depression in half by the year 2050. The mammoth undertaking will rely on platforms developed by the new Institute for Precision Health, which will harness the power of big data and genomics to move toward individually tailored treatments and health-promotion strategies.On the same 419 acres of land, researchers across the spectrum, from the laboratory bench to the patient bedside, are ushering in a potentially game-changing approach to turning the body ’s immune defenses again...

Neuroscientists show deep brain waves occur more often during navigation and memory formation
FINDINGSUCLA neuroscientists are the first to show that rhythmic waves in the brain called theta oscillations happen more often when someone is navigating an unfamiliar environment, and that the more quickly a person moves, the more theta oscillations take place — presumably to process incoming information faster.In an unexpected finding, theta oscillations were most prominent in a blind person who relied on a cane to move. The scientists hypothesized that a sightless person explores a strange environment through multiple senses, which would require more brain activity to process the extra sensory input.BACKGROUNDTheta o...

UCLA scientists pioneer new method for watching brain cells interact in real time
An advance by UCLA neuroscientists could lead to a better understanding of astrocytes, star-shaped brain cells that are believed to play a key role in neurological disorders like Lou Gehrig ’s, Alzheimer’s and Huntington’s diseases.Reported in Neuron, the new method enables researchers to peer deep inside a mouse ’s brain and watch astrocytes’ influence over the communication between nerve cells in real time. The test relies on fluorescence resonance energy-transfer microscopy, or FRET microscopy, a technique that uses light to measure the tiniest of distances between molecules. The UCLA team focused on astrocyt...

UCLA biologists ‘transfer’ a memory
UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. This research could lead to new ways to lessen the trauma of painful memories with RNA and to restore lost memories.“I think in the not-too-distant future, we could potentially use RNA to ameliorate the effects of Alzheimer’s disease or post-traumatic stress disorder,” said David Glanzman, senior author of the study and a UCLA professor of integrative biology and physiology and of neurobiology. The team’sresearch is published May 14 in eNeuro, the online journa...

New therapy spurs nerve fibers to regrow through scar tissue, transmit signals after spinal cord injury in rodents
Neuroscientists at UCLA, Harvard University and the Swiss Federal Institute of Technology have identified a three-pronged treatment that triggers axons — the tiny fibers that link nerve cells and enable them to communicate — to regrow after spinal cord injury in rodents. Not only did the axons grow through scars, they could also transmit signals across the damaged tissue.If researchers can produce similar results in human studies, the findings could lead to a therapy to regrow axon connections in people living with spinal cord injury, potentially restoring function. Nature publishes the research in its Aug. 29 onl...

How to stay healthy and happy through the decades
Successful aging can be the norm, says UCLA psychology professor Alan Castel in his new book, “Better with Age: The Psychology of Successful Aging” (Oxford University Press). Castel sees many inspiring role models of aging. French Impressionist Claude Monet, he notes, began his beloved water lily paintings at age 73.Castel cites hundreds of research studies, including his own, combined with personal accounts from older Americans, including Maya Angelou, Warren Buffett, John Wooden, Bob Newhart, Frank Gehry, David Letterman, Jack LaLanne, Jared Diamond, Kareem Abdul-Jabbar, John Glenn and Vin Scully.Castel notes that ar...

Study shows how serotonin and a popular anti-depressant affect the gut ’s microbiota
In this study, we were interested in finding out why they might do so,” said Hsiao, UCLA assistant professor of integrative biology and physiology, and of microbiology, immunology and molecular genetics in the UCLA College; and of digestive diseases in the David Geffen School of Medicine at UCLA.Hsiao and her research group reported in the journal Cell in 2015 that in mice, a specific mixture of bacteria, consisting mainly of Turicibacter sanguinis and Clostridia, produces molecules that signal to gut cells to increase production of serotonin. When Hsiao’s team raised mice without the bacteria, more than 50% of t...

How our brains create breathing rhythm is unique to every breath
Breathing propels everything we do, so its rhythm must be carefully organized by our brain cells, right?Wrong.Every breath we take arises from a disorderly group of neurons — each one like a soloist belting out its song before it unites with other neurons to harmonize on a fresh breath.That ’s the gist ofa UCLA study published March 3 in the online edition of Neuron.“We were surprised to learn that how our brain cells work together to generate breathing rhythm is different every time we take a breath,” saidJack Feldman, the study ’s senior author, a professor of neurobiology at the David Geffen School of Medic...

New study pinpoints how the brain ’s inner clock measures seconds
FINDINGSUCLA neuroscientistsstudying how the brain measures time in secondsintroduced mice to two different scents. The mice learned that one odor predicted the arrival of a sweet liquid reward after three seconds, while the other predicted the reward after six seconds.The mice started licking the spout earlier in anticipation of the reward after they sniffed the first scent than when they smelled the second.While the mice responded to the two stimuli, researchers observed activity intwo regions of their brains: the striatum and the premotor cortex,which provides input to the striatum. They found that while both regions en...

Q & A: Dr. Thomas Rando on preventing age-related diseases and turning discoveries into cures
For Dr. Thomas Rando, the path to becoming a physician-scientist began with something that hedidn ’t learn in high school biology.After one class that touched on the connections between neurons and muscle fibers, Rando took it upon to himself to find all the information he could about how cells communicate through electrical signals.Soon, he began pursuing that interest at Harvard University, where he completed his undergraduate work, a doctorate in cell and developmental biology and his medical degree.Rando joined the neurology faculty at the Stanford University School of Medicine in 1995.There, he founded a clinic to t...
