Caffeinated coffee helps to minimize reductions in attention and cognitive function

A new study exploring the impact of repeated sleep loss during a simulated working week has found that consuming caffeinated coffee during the day helps to minimize reductions in attention and cognitive function, compared to decaffeinated coffee.

Metabolites may be predictive indicators for recurrent major depressive disorder

Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.

Many light smokers meet the criteria for nicotine addiction

Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment.

Study shows how the brain navigates places and tracks someone else in the same location

As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location.

Study shows cocaine use in mice leads to formation of synapses

Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors.

New findings help to better understand the genetics of neuropsychiatric disorders

A new study led by NorthShore University HealthSystem (NorthShore) and the University of Chicago took a novel approach to identifying SNPs influencing the risk of neuropsychiatric disorders like schizophrenia, bipolar and major depressive disorder, the institutions announced today.

Study shows cathepsin B can be used as biomarker for traumatic brain injury

Scientists at the Walter Reed Army Institute for Research (WRAIR) have recently demonstrated that cathepsin B, a well-studied protein important to brain development and function, can be used as biomarker, or indicator of severity, for traumatic brain injury.

Brain's dedicated immune cells clear paths through 'scaffolding' to let neurons talk

To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons' long, branching tentacles dock neurons together so they can talk.

Region-specific atlas reveals genome linked to human embryonic brain development

An adjusted sequence of genetic events should occur to allow the budding brain of a human embryo to turn into the organ that regulates human consciousness.

Disrupted circadian rhythms in older adults linked to increased risk of Parkinson's disease

Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study by scientists at the UC San Francisco Weill Institute for Neurosciences who analyzed 11 years of data for nearly 3,000 independently living older men.

Eating one meal high in saturated fat may affect our ability to focus

Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate - not great news for people whose diets have gone south while they're working at home during the COVID-19 pandemic.

Researchers discover group of genes with altered expression in autism

Autism has long been associated only with behavioral and environmental factors, but the role of genetics in its development is now increasingly evident. Some 100 genes have been found to play a role in autism spectrum disorder, and another thousand are being studied to the same end.

Study pinpoints a key brain region for controlling binge drinking

A team of National Institutes of Health-funded researchers at the Medical University of South Carolina has found that deactivating a stress-signaling system in a brain area known for motivation and emotion-related behaviors decreases binge drinking.
