UCLA scientists hunt down origin of Huntington's disease in the brain
The gene mutation that causes Huntington's disease appears in every cell in the body, yet it kills only two types of brain cells. Why? UCLA scientists used a unique approach to switch the gene off in individual brain regions and zero in on those that play a role in causing the disease in mice.
Published in the April 28 online edition of the journal Nature Medicine, the research sheds light on where Huntington's starts in the brain. It also suggests new targets and routes for therapeutic drugs to slow the devastating disease, which strikes an estimated 35,000 Americans.
"From Day One of conception, the mutant gene that caus...

Brain’s reaction to virtual reality should prompt further study, suggests new research by UCLA neuroscientists
UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes.
“The pattern of activity in a brain region involved in spatial learning in the virtual world is completely different than when it processes activity in the real world,” said Mayank Mehta, a UCLA professor of physics, neurology and neurobiology in the UCLA College and the study’s senior author. “Since so many people are using virtual r...

Lost memories might be able to be restored, new UCLA study indicates
New UCLA research indicates that lost memories can be restored. The findings offer some hope for patients in the early stages of Alzheimer’s disease.
For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses.
“Long-term memory is not stored at the synapse,” said David Glanzman, a senior author of the study, and a UCLA professor of integrative biology and physiology and of neurobiology. “...

Has Brazil found the way to better health care?
Under Brazil’s family health program, when a woman learns that she is pregnant, she contacts her local community health agent, who often is a neighbor.
Typically, the agent visits her home to arrange an appointment with the neighborhood’s family health team, and the woman visits the health center for an assessment by a nurse assistant and a physician. During the pregnancy, if she misses a prenatal care appointment, the agent checks in on her at home and helps her reschedule her visit. Any prenatal medications she needs are provided free of charge.
Brazil — home to the world’s fifth-largest population and seventh-l...

Expert advice: How to help an addicted friend or family member get help
Experts understand that addiction isn’t a weakness or moral failing; it’s an illness, much like cancer or heart disease. And It often falls to family members and friends to convince their addicted loved one to seek help. The task can feel like negotiating an emotional minefield with anger, obfuscation and denial among the likely outcomes. How do you know if there’s a problem, when do you intervene and how? Dr. Timothy Fong, associate clinical professor of psychiatry and director of the UCLA Addiction Medicine Clinic, provided guidance in the July 2015 issue of UCLA Magazine. An edited version of the article fo...

UCLA–Tel Aviv study suggests REM sleep helps the brain capture snapshots of dream images
When we sleep, we experience our most vivid dreams and vigorous brain activity during the rapid eye movement, or REM phase. Although scientists have long suspected that our eyes flicker in response to what our unconscious mind sees in our dreams, no one has been able to prove it.
Now, an international team of researchers led by UCLA’s Dr. Itzhak Fried is the first to demonstrate that during dreams, our eyes and brains respond similarly to how they react to images when we’re awake. Published in the Aug. 11 online edition of Nature Communications, the findings offer a rare glimpse into the working of individual brain...

High-fructose diet hampers recovery from traumatic brain injury
A diet high in processed fructose sabotages rats’ brains’ ability to heal after head trauma, UCLA neuroscientists report.
Revealing a link between nutrition and brain health, the finding offers implications for the 5.3 million Americans living with a traumatic brain injury, or TBI. According to the Centers for Disease Control and Prevention, an estimated 1.7 million people suffer a TBI each year, resulting in 52,000 annual deaths
“Americans consume most of their fructose from processed foods sweetened with high-fructose corn syrup,” said Fernando Gomez-Pinilla, a professor of neurosurgery and integrative biology an...

New app lets you check air quality as easily as checking the weather
Yareli Sanchez lives in Los Angeles and jogs regularly, but she never used to know if the day’s air quality was bad until after she had already set out for a run — her chest would tighten and it would become hard to breathe. She knew poor air quality triggered her asthma, but she didn’t have a convenient way to check the day’s pollution levels.
For the past few months, instead of using trial-and-error, she’s checked UCLA’s new AirForU app, which uses GPS data to give her local air quality ratings. The app is useful for anyone in the U.S. who sees a hazy skyline and wonders how safe it is to breathe outside air...

At UCLA, it's medicine 2.0
Tucked deep in the basement of UCLA’s Center for the Health Sciences is a room that looks more like an inventor’s fantasy workshop than the medical research facility it is. Tables are piled high with tools, electronics, prototype equipment parts and a few stray robotic arms. Posters on the wall describe pending projects in dense technical language with accompanying photos of futuristic devices.
This hidden space is where scientists are working at the very forefront of technological advances in medicine. Its assemblage of smarts, parts and computers is contributing to an emerging era of personalized, tech-enabled health...

Head injuries can alter hundreds of genes and lead to serious brain diseases, UCLA biologists report
Head injuries can harm hundreds of genes in the brain in a way that increases people ’s risk for a wide range of neurological and psychiatric disorders, UCLA life scientists report.The researchers identified for the first time master genes that they believe control hundreds of other genes which are linked to Alzheimer ’s disease, Parkinson’s disease, post-traumatic stress disorder, stroke, attention deficit hyperactivity disorder, autism, depression, schizophrenia and other disorders.Knowing what the master genes are could give scientists targets for new pharmaceuticals to treat brain diseases. Eventually, scientists...

Scientists identify brain cells involved in Pavlovian response
In his famous experiment, Russian scientist Ivan Pavlov rang a bell each time he fed his dogs. Soon, the dogs began drooling in anticipation when they heard the bell, even before food appeared.Now, a UCLA study has traced the Pavlovian response to a small cluster of brain cells — the same neurons that go awry during Huntington’s disease, Parkinson’s disease and Tourette’s syndrome. Published March 22 in the journal Neuron, the research could eventually help scientists identify new approaches to diagnosing and treating these neurological disorders.“Species survive because they’ve learned how to link sensory cue...

UCLA neuroscientists use weak electrical signal to stimulate human brain and improve memory
FINDINGSNeuroscientists at the David Geffen School of Medicine at UCLA have discovered precisely where and how to electrically stimulate the human brain to enhance people’s recollection of distinct memories. People with epilepsy who received low-current electrical pulses showed a significant improvement in their ability to recognize specific faces and ignore simila r ones.Eight of nine patients ’ ability to recognize the faces of specific people improved after receiving electrical pulses to the right side of the brain’s entorhinal area, which is critical to learning and memory. However, electrical stimulation deli...
