UC Davis neuroscientists advance learning and memory research to decode how our brains work


For astrophysicists, the final frontier is outer space, but ask a neuroscientist, and the greatest quest for scientific exploration lies within your brain. 

Vastly more advanced than any supercomputer, the complexity and versatility of the human brain is awe-inspiring. Of all its abilities, learning from new experiences might be the most powerful and astounding feature. But how does learning occur? And how do we remember what we learn? 

These are the fundamental questions researchers at the UC Davis Center for Neuroscience are asking. To find answers, they’re investigating the brain at many levels—from the smallest molecules that make our brains work to the thought patterns that give our world meaning.

Why You Forget Names Immediately—And How to Remember Them


Of all the social gaffes, none is perhaps more common than meeting a new person, exchanging names and promptly forgetting theirs — forcing you to either swallow your pride and ask again, or languish in uncertainty forever.

Why do we keep making this mistake? There are a few potential explanations, says Charan Ranganath, the director of the Memory and Plasticity Program at the University of California, Davis.

How Experience Changes Basics of Memory Formation

We know instinctively that our experiences shape the way we learn. If we are highly familiar with a particular task, like cooking for example, learning a new recipe is much easier than it was when we were a novice. New research from the University of California, Davis, shows that experience also changes the way our neurons become plastic and form new memories.

Discovering Curiosity: Age-Related Hearing Loss


As our bodies age, we all face some decline in our senses, and among the senses most susceptible to deterioration is hearing.

Hearing loss is a substantial problem for society. It’s the third most common physical condition after arthritis and heart disease and about 30 percent of adults between ages 65 and 74 and nearly half of people over 75 experience some difficulty hearing.  It’s a social problem, one that can lead to isolation and depression.

History of mistrust complicates study of dementia in African-Americans


The question came as a shock to Dorothy Reeves: Would she be willing to donate her husband's brain for research?

She knew dementia would steadily take Levi Reeves' memories of their 57-year marriage, his remaining lucidity and, eventually, his life. But to let scientists take his brain after he died? That seemed too much to ask.

Mice made with CRISPR usher in new era of autism research


Researchers have debuted two mouse models of autism made using the gene-editing tool CRISPR. Both strains lack one functional copy of CHD8, a gene with strong ties to autism.

CRISPR allows researchers to quickly and efficiently insert specific mutations into single-cell mouse embryos. Several teams have used the method to make mouse models for other conditions, including Rett syndrome, an autism-related condition. The new mice represent the first use of the method to make models expressly for autism.

The riddle of CHD8 haploinsufficiency in autism spectrum disorder


Autism spectrum disorders (ASDs) are a group of neurodevelopmental conditions defined by social and communication deficits accompanied by repetitive and stereotyped behaviors. The core symptoms of ASDs are rarely isolated and most often coexist with other conditions, such as intellectual disability and epilepsy. ASDs have a strong genetic basis as demonstrated by recurrence risk in families and twin studies. In recent years, genetic studies have identified several chromatin remodeling genes with causal roles in neurodevelopmental disorders.

Curious about Curiosity


Neuroscientists are beginning to understand the connections.

Curiosity’s powers extend above and beyond its perceived potential contributions to usefulness or benefits. It has shown itself to be an unstoppable drive. The efforts humans have invested, for instance, in exploring and attempting to decipher the world around them, have always far exceeded those needed for mere survival. It seems that we are an endlessly curious species, some of us even compulsively so. University of Southern California neuroscientist Irving Biederman says human beings are designed to be “infovores,” creatures that devour information.

The next big challenge in AI could be teaching computers how to think like humans


Charan Ranganath has dedicated his professional life to studying how the human brain works. Now the UC Davis psychology professor is pushing that research into new frontiers by teaching computers how to slow down and mimic that same complicated but imperfect organ.

Ranganath and his team are putting to use a $7.5 million grant from the Department of Defense to develop a computational model that emulates how memory functions in the real world. The DOD is hoping to use that model to help predict and prevent terrorist activities as well as for other national security purposes. Ranganath is taking on that task by leading a team of five other scientists from Princeton, Harvard, Washington University in St. Louis and New York University.

Improving the Lives of Families


UC Davis researchers search tirelessly for solutions for families affected by autism.

When 16-year-old Kira Duley wants to tell her mom how she's feeling, she does a Google image search.  For love, she points to a heart.  For sad, a frowning emoji.  For lonely, a photo of a woman standing alone on a beach, looking off into a sunset. 

Kira communicates this way because she has autism spectrum disorder (ASD).  Although autism presents itself differently in different people, 25 percent of peole with autism- like Kira- do not develop spoken language.

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


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.
