Experimental implant shows promise for restoring voluntary movement after spinal cord injury

UCLA scientists test electrical stimulation that bypasses injury; technique boosts patient’s finger control, grip strength up to 300 percent

A spinal stimulator being tested by doctors at Ronald Reagan UCLA Medical Center is showing promise in restoring hand strength and movement to a California man who broke his neck in a dirt bike accident five years ago. (more…)

Mutation Stops Worms from Getting Drunk

AUSTIN, Texas — Neuroscientists at The University of Texas at Austin have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.

The scientists accomplished this feat by inserting a modified human alcohol target into the worms, as reported this week in The Journal of Neuroscience. (more…)

Songbirds’ Brains Coordinate Singing with Intricate Timing, Study Shows

Research may help explain how human brain governs speech

In an article in the current issue of Nature, neuroscientist Daniel Margoliash and colleagues show, for the first time, how the brain is organized to govern skilled performance—a finding that may lead to new ways of understanding human speech production. (more…)

For This Doctor, Hope Amidst Fear is the Best Medicine

Dr. Alfredo Quiñones-Hinojosa may not be able to cure his patients’ brain cancer, but there is one thing that the internationally renowned neurosurgeon and neuroscientist can provide them with: hope.

During a recent visit to campus Quiñones-Hinojosa discussed his journey from a migrant farm worker to a doctor who researches the deadliest form of brain cancer, glioblastomas. His talk was sponsored by La Casa Cultural Center, the Latino Cultural Center at Yale. (more…)

Mammalian Brain Knows Where It’s at

A new study in the journal Neuron suggests that the brain uses a different region than neuroscientists had thought to associate objects and locations in the space around an individual. Knowing where this fundamental process occurs could help treat disease and brain injury as well as inform basic understanding of how the brain supports memory and guides behavior.

PROVIDENCE, R.I. [Brown University] — Where are you?

Conventional wisdom in brain research says that you just used your hippocampus to answer that question, but that might not be the whole story. The context of place depends on not just how you got there, but also the things you see around you. A new study in Neuron provides evidence that a different part of the brain is important for understanding where you are based on the spatial layout of the objects in that place. The finding, in rats, has a direct analogy to primate neuroanatomy. (more…)

UCLA Scientists Boost Memory By Stimulating Key Site in Brain

*Mechanism holds potential for improving recall in dementia patients*

Have you ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory.

UCLA neuroscientists have demonstrated that they can strengthen memory in human patients by stimulating a critical junction in the brain. Published in the Feb. 9 edition of the New England Journal of Medicine, the finding could lead to a new method for boosting memory in patients with early Alzheimer’s disease. (more…)

Bird Song Yields a New Understanding of Cooperation

*A bird duet springs forth from each bird’s knowledge of the entire song*

The site of a volcano isn’t the first place one might think of to study cooperation. But neuroscientist Eric Fortune of Johns Hopkins University and colleagues went to the slopes of Antisana volcano in Ecuador to study cooperation as it plays out with a very special songbird, the plain-tailed wren. Funded in part by the National Science Foundation, the researchers report their observations in the Nov. 4, 2011, issue of Science.

Rapidly alternating their singing back and forth, female and male wrens cooperate to sing a duet that sounds as if a single bird sang it. The researchers assumed that the brain of each bird would have a memory of its own part of the duet, and also have a memory of the cues from its partner. They were surprised to find that both brains had a record of the complete duet–a performance that neither bird can do by itself. (more…)
