Irvine, Calif., Nov. 30, 2022 — Researchers at the University of California, Irvine have discovered that removal of cilia from the brain’s striatum region impaired time perception and judgment, revealing possible new therapeutic targets for mental and neurological conditions including schizophrenia, Parkinson’s and Huntington’s diseases, autism spectrum disorder, and Tourette syndrome.
Irvine, Calif., Nov. 29, 2022 — When the U.S. Food and Drug Administration gave controversial accelerated approval to the first Alzheimer’s drug in nearly 20 years, it had a surprising impact on attitudes about research into the disease. A survey by University of California, Irvine neuroscientists has found news coverage of the FDA’s decision made the public less willing to volunteer for Alzheimer’s pharmaceutical trials.

Irvine, Calif., June 21, 2022 — If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or more broadly, how well can you focus in school or at work? In the language of psychologists, does “near transfer” predict “far transfer”? A team of psychologists from the University of California, Irvine and the University of California, Riverside reports in Nature Human Behavior that people who show near transfer are more likely to show far transfer.

For the first time, researchers have shown that there is a genetic component underlying the amazing spatial memories of Mountain Chickadees. Although the genetic basis for spatial memory has been shown for humans and other mammals, direct evidence of that connection has never before been identified in birds.
To prevent wrongful convictions, only the first identification of a suspect should be considered.
SUNY Geneseo’s Jason Ozubko is the first author on a recent paper that looks at a type of memory glitch called a “recognition failure.” It’s when you can come up with a word—like the name of a restaurant you’re struggling to remember—without being sure that the name you just blurted out is the correct name.
Recently, the National Institutes of Health (NIH) awarded researchers at the Icahn School of Medicine at Mount Sinai a five-year grant to out whether exposing patients to a combination of light therapies will slow Alzheimer’s debilitating effects.
Has the scent of freshly baked chocolate chip cookies ever taken you back to afternoons at your grandmother’s house? Has an old song ever brought back memories of a first date? The ability to remember relationships between unrelated items (an odor and a location, a song and an event) is known as associative memory.
Bristol-led research has identified specific drug targets within the neural circuits that encode memories, paving the way for significant advances in the treatment of a broad spectrum of brain disorders.
In a study of rodents, scientists at the Icahn School of Medicine at Mount Sinai discovered that a part of the brain traditionally thought to control typing the old habits may also play a critical role in learning the new actions. The results, published on August 25th in Nature Communications, suggest that this process involves a delicate balance in the activity of two neighboring neural circuits: one dedicated to new actions and the other to old habits
Cedars-Sinai researchers have identified a set of brain cells that, when affected by epilepsy, cause memory impairment in patients with a particular type of the disorder called temporal lobe epilepsy (TLE).
With hopes to capitalize on the smell factor in flavor development, researchers are exploring how the route an aroma takes to get to the olfactory system, through the nose or the back of the throat, influences our response to the scent in question.
If you didn’t have a brain, could you still figure out where you were and navigate your surroundings?
Irvine, Calif., June 21, 2021 — A large-scale meta-analysis led by University of California, Irvine researchers provides the strongest evidence yet of which blood pressure medications help slow memory loss in older adults: those that can travel out of blood vessels and directly into the brain. The findings, published in the American Heart Association journal Hypertension, will be of interest to the 91 million Americans whose blood pressure is high enough to warrant medication, as well as the doctors who treat them.

New research led by a University of Georgia faculty member in collaboration with a University of Southern California research group has shown in a rodent model that daily consumption of sugar-sweetened beverages during adolescence impairs performance on a learning and memory task during adulthood. The group further showed that changes in the bacteria in the gut may be the key to the sugar-induced memory impairment.

More than a dozen drugs are known to treat symptoms such as hallucinations, erratic behaviors, disordered thinking and emotional extremes associated with schizophrenia, bipolar disorder and other severe mental illnesses. But, drug treatments specifically able to target the learning, memory and concentration problems that may accompany such disorders remain elusive.
Even though people tend to remember fewer details about past events as time goes by, the details they do remember are retained with remarkable fidelity, according to a new study. This finding holds true regardless of the age of the person or the amount of time that elapsed since the event took place.
Research from the Department of Psychological & Brain Sciences in Arts & Sciences finds a new relationship between memory and the ability to incorporate changes into one’s understanding of the world.
Women who work in the paid labor force in early adulthood and middle age may have slower memory decline later in life than women who do not work for pay, according to a new study published in the November 4, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers found an association between working for pay and slower memory decline regardless of a woman’s marital or parenthood status.

The findings could have important implications for improving the accuracy of everyday memory and eyewitness testimony.
A research team highlights the mechanisms underlying memory and learning capacity – specifically, how our brains process, store and integrate information.
“Older adults might be representing events in different ways, and transitions might be picked up differently than, say, a 20-year-old,” said Zachariah Reagh, assistant professor of psychological and brain sciences in Arts & Sciences. Reagh looked at fMRI images to study memory differences in different age groups.
Chemotherapy usually cures children diagnosed with acute lymphoblastic leukemia (ALL), but the treatment may hamper brain development and impact key cognitive functions including sensory processing, memory, and attention. Researchers at Albert Einstein College of Medicine, Children’s Hospital at Montefiore (CHAM), and Rutgers Cancer Institute of New Jersey have received a five-year, $4.6 million grant from the National Institutes of Health (NIH) to determine how chemotherapy exerts its damaging effects on the brain. Their long-term objective is to use this information to develop protective interventions that can prevent permanent harm.
Neuroscientist at the University at Albany will research how different types of memories are formed and stored at different times of the day, and how they are modified by different types of cells
