New Research Suggests Cerebellum May Play Important Role in Autism

Researchers in the College of Biological Sciences have received a grant to study the role of the cerebellum in autism. “We need a more holistic understanding of the brain circuits that drive this disorder,” says Alex Nord, an associate professor of neurobiology, physiology and behavior (NPB), and a researcher at the Center for Neuroscience (CNS). “The cerebellum is a key component that has been largely overlooked until recently.”

$15 Million Grant Will Support Study on the Role of the Thalamus in Cognitive Control and Schizophrenia

When it comes to brain anatomy, the thalamus occupies a humble position.  It sits at the top of our brainstem — an apparent vestige of our reptilian past — and is dwarfed by the massive, wrinkled cerebral cortex, which sits above it. The cortex is often credited as the throne of human intellect. But a team of researchers across the country, with UC Davis led by W. Martin Usrey, sees the thalamus as a critical coordinator of our thoughts and perceptions – and pivotal in human disease.

A Distinguished Legacy: Recognizing Barbara Horwitz

In the first part of the UC Davis Emeriti spring celebration, one of the most distinguished professors of the UC Davis emeriti family, Barbara A. Horwitz, was honored for more than five decades of service as a Professor of Neurobiology, Physiology, and Behavior within the College of Biological Sciences.

Kept secret until the day of the event because she dislikes the spotlight, the surprise homage included anecdotes from various colleagues, including Chancellor Gary May.

Wilsaan Joiner Named 2023 Chancellor's Fellow

Wilsaan Joiner, a professor in the Department of Neurobiology, Physiology and Behavior, was among this year’s cohort of Chancellor’s Fellows.

“Our newest fellows represent the very best of UC Davis and I congratulate them,” Chancellor Gary S. May said in announcing the new fellows. “The knowledge, expertise and excellence these faculty demonstrate across a range of disciplines positively impacts our university’s mission of research, teaching and public service.”

How Dragonflies Catch Prey in Midair

Despite their small size, dragonflies are arguably one of the most impressive predators in the animal kingdom. According to Rachel Crane, a biologist at the University of California Davis, dragonflies often catch up to 95% of the prey they go after, a rate she described as “wildly high compared to where most predators are.” 

More incredible still, this prey capture all happens in midair.

“Dragonflies are doing these really, really fast, high-speed aerial captures,” said Crane. 

Breaking the Loop Leading to Muscular Fibrosis

A team of UC Davis researchers is on a mission to solve a key mystery in the formation of muscular fibrosis. The researchers are studying why special stem cells known as fibro-adipogenic progenitors (FAPs) get derailed from normal muscle regeneration following injury, and instead produce excess material that can lead to fibrosis. The team may have unlocked a way to prevent these cells from getting stuck in an endless loop of collagen production, causing fibrotic muscles. 

Making Prosthetics More Lifelike

David Brockman, a retired CalFire captain and avid outdoorsman, built a deck in the backyard of his home last year, without the use of his dominant right hand, which he lost in an accident. The prosthetic hand he used instead was a crude but functional steel hook-and-harness device.

Brockman has tried other artificial limbs, including a high-tech prosthesis called a myoelectric. It looks like a hand and works by using electrical signals from muscles in the forearm. But that one just didn’t work for him.
