An old drug gets a new price to fight a rare disease: $89,000 a year

2.10.2017

An old steroid treatment, long available outside the United States, received approval this week for a rare disease that afflicts about 15,000 Americans. Though not previously approved in the United States, the drug, deflazacort, has for years been available to patients suffering from the devastating and fatal disease Duchenne muscular dystrophy; families can import it from abroad for about $1,200 per year on average.

The new list price for the drug? $89,000 a year.

What Do Genetic Links Between Cancer And Autism Mean For Treatment?

2.9.2017

In 1997 a Cleveland-based researcher studying a rare, sometimes-cancerous condition noticed that an unusually high percentage of her patients also had a particular type of autism. She eventually discovered that both conditions shared the same genetic mutation.

Since then, a number of other cancer genes have been found in some types of autism, and a recent report out of the University of California Davis says 43 genes thought to be involved in autism are also associated with cancer.

Forget Me Not: The Harrowing Tale of H. M.'s Brain (Excerpt)

2.9.2017

Michael D. Lemonick explains how a postmortem study of the most celebrated amnesic in history went awry

I pulled the New York Times out of its plastic delivery bag on the morning of December 5, 2008, unfolded the paper, and read this headline on the front page: “H.M., an Unforgettable Amnesiac, Dies at 82.”

He was certainly unforgettable to me. I’d first read about H.M. in my freshman psychology textbook at college, in the fall of 1971, less than twenty years after the experimental surgery that robbed him of most of his existing memories and also of ability to form new ones. The idea of living in a perpetual “now” seemed appalling, and, along with the two hundred or so other students in the class, I tried to imagine what such an existence might be like. Naturally, I failed.

Why Scientists Are Still Flummoxed by Alzheimer's

12.7.2016

The brain is amazing and complicated

Preventing memory loss and restoring it once it’s gone is the holy grail of brain science. In the United States alone, an estimated 5 million people are living with Alzheimer’s disease. But recently, unexpected and disappointing findings have underlined just how difficult it is to develop therapies for cognitive decline.

Heavy Screen Time Rewires Young Brains, For Better And Worse

11.19.2016

There's new evidence that excessive screen time early in life can change the circuits in a growing brain.

Scientists disagree, though, about whether those changes are helpful, or just cause problems. Both views emerged during the Society for Neuroscience meeting in San Diego this week.

A pregnant woman’s immune response could lead to brain disorders in her kids

8.18.2016

Pregnant women, like everyone, get sick. And like everyone else, their bodies try to fight infection and, importantly, keep it from reaching the growing fetus.

If the mother’s immune system successfully defeats the virus before the developing baby is exposed or if the virus never crosses the placenta, is harm averted?

Researchers Temporarily Turn off Brain Area to Better Understand Function

7.20.2016

Capitalizing on experimental genetic techniques, researchers at the California National Primate Research Center, or CNPRC, at the University of California, Davis, have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain.

The research suggests that alterations in the functional connectivity of the brain in humans may be used to determine the sites of pathology in complex disorders such as schizophrenia and autism.

Exercise is really, really good for your brain

3.1.2016

Physical exercise is good for your brain. And I mean really good for it. The brain burns a ton of energy during exercise, much more, even, than if you were thinking really hard about something really complicated. New research has discovered just what the brain does with all that extra energy.

"From a metabolic standpoint, vigorous exercise is the most demanding activity the brain encounters, much more intense than calculus or chess, but nobody knows what happens with all that energy," says the paper’s lead author Richard Maddock, UC Davis research professor of psychiatry and behavioral sciences and affiliated faculty of the Center for Neuroscience.

Beam me up, Scotty? Turns out your brain is ready for teleportation

2.26.2016

Given recent advances in teleportation, it's reassuring to know that the human brain's navigation system appears to work just fine when we're beamed from place to place.

People who experienced virtual teleportation in a video game were able to mentally navigate to known destinations without relying on visual information or perceived motion, according to a study published Thursday by the journal Neuron. And during "teleportation," their brains produced a distinctive electrical signal that's associated with navigation.

Memory reply prioritizes high-reward experiences

2.11.2016

Why do we remember some events, places and things, but not others? Our brains prioritize rewarding memories over others, and reinforce them by replaying them when we are at rest, according to new research from the University of California, Davis, Center for Neuroscience, published Feb. 11 in the journal Neuron.

“Rewards help you remember things, because you want future rewards,” said Professor Charan Ranganath, a UC Davis neuroscientist and senior author on the paper. “The brain prioritizes memories that are going to be useful for future decisions.”

What happened when? How the brain stores memories by time

3.12.2014

Before I left the house this morning, I let the cat out and started the dishwasher. Or was that yesterday? Very often, our memories must distinguish not just what happened and where, but when an event occurred — and what came before and after. New research from the University of California, Davis, Center for Neuroscience shows that a part of the brain called the hippocampus stores memories by their "temporal context" — what happened before, and what came after.
