Asthma is associated with memory difficulties in children, and early onset of asthma may exacerbate memory deficits, according to a new study from the University of California, Davis.

The Roots of Fear: Understanding the Amygdala

Andy Fell — October 30, 2024 - 10:50am

Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists at the University of California, Davis have identified new clusters of cells with differing patterns of gene expression in the amygdala of humans and non-human primates. The work could lead to more targeted treatments for disorders such as anxiety that affect tens of millions of people.

Adolescents who had emotional support from friends and relatives, and who were biologically prepared to respond well to others, were more likely to exhibit prosocial behavior and empathy for others as they entered young adulthood, compared to adolescents without that kind of backing. The findings came from a recent University of California, Davis, study of Mexican-origin teens living in the United States.

Alfred Hitchcock observed that “There is no terror in the bang, only in the anticipation of it.” A common way to build suspense in a movie scene is for the audience to know something bad is going to happen, but not when it is going to happen. But how does uncertainty work to ratchet up our anxiety? In a recent paper in the journal Computational Psychiatry, researchers at the University of California, Davis, Department of Psychology take a deeper look into what builds fear.

Everyone ruminates about the bad things that happen to them. Whether it’s a nasty breakup, an embarrassing failure or simply when someone is mean, it can be hard to stop thinking about what happened and why. For people who ruminate too much, this negative thought pattern can cause lasting problems with mental health.

Higher Conscientiousness Linked to Less Risk of Dementia Diagnosis

Andy Fell — November 29, 2023 - 8:00am

People with personality traits such as conscientiousness, extraversion and positive affect are less likely to be diagnosed with dementia than those with neuroticism and negative affect, according to a new analysis by researchers at the University of California, Davis and Northwestern University. The difference was not linked to physical damage to brain tissue found in dementia patients, but more likely to how certain personality traits help people navigate dementia-related impairments.
