UrduA study examined the effects of anthropogenic noise on cognition, beak color, and growth in the zebra finch. Researchers first tested adult zebra finches on a battery of cognition assays while they were exposed to playbacks of urban noise versus birds tested without noise. Urban noises caused the birds to take longer to learn a novel foraging task and to learn an association-learning task. Urban noise exposure also resulted in treated males to develop less bright beak coloration, and females developed beaks with brighter orange coloration, respectively, than untreated birds. Findings suggest that urban noise exposure may affect morphological traits, such as beak color, which influence social interactions and mate choice.

Benefits of acute aerobic exercise on cognitive function: Why do 50% of studies find no connection?
Over the past 20 years, many studies have investigated the effects of acute aerobic exercise on cognitive performance.
Memory Biomarkers Confirm Aerobic Exercise Helps Cognitive Function in Older Adults
Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer’s.

Schools with a higher proportion of students of color and from households experiencing poverty were exposed to more peak pollution days than were schools serving middle- to upper- class and predominately white students.
Study Provides First Evidence of a Relationship between a Bird’s Gut and its Brain
A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird’s gut microbiome and its brain.

Vitamin D Boosts Chances of Walking After Hip Fracture
Senior citizens who are not vitamin D deficient have a better chance of walking after hip fracture surgery, according to a Rutgers-led study. The findings in The American Journal of Clinical Nutrition suggest that vitamin D deficiency could limit mobility in older adults, said senior author Sue Shapses, a professor in the Department of Nutritional Sciences at the School of Environmental and Biological Sciences at Rutgers University–New Brunswick.
Neighborhood Features and One’s Genetic Makeup Interact to Affect Cognitive Function
Few studies have examined how the neighborhood’s physical environment relates to cognition in older adults. Researchers categorized 4,716 individuals by apolipoprotein E (APOE) genotype – a genetic risk factor for Alzheimer’s disease (AD) to determine if there are cognitive benefits of living in neighborhoods with greater access to social, walking and retail destinations. Results showed that the positive influence of neighborhood environments on cognition are strongest among those who are at the lowest risk for AD, specifically APOE ε2 carriers.
Activating immune cells could revitalize the aging brain, study suggests
Researchers at Albany Medical College in New York have discovered that a specific type of immune cell accumulates in older brains, and that activating these cells improves the memory of aged mice. The study, which will be published February 5 in the Journal of Experimental Medicine (JEM), suggests that targeting these cells might reduce age-related cognitive decline and combat aging-associated neurodegenerative disease in humans.
Calculated Surprise Leads to Groundbreaking Discovery in Cognitive Control Research
To better understand how motivational control processes help maximize performance when faced with task challenges, researchers used functional magnetic resonance imaging (fMRI) and provide fascinating insights into the role of the dorsal anterior cingulate cortex (dACC) as a component network of brain regions that support motivated behavior. They have unified conflicting findings by discovering that the single mechanism of surprise best accounts for activity in dACC during a task requiring motivated control.
Cerebellum and cognition: Impact of co-use of alcohol and cigarettes
There is consistent evidence that having an alcohol use disorder is associated with abnormalities in the cerebellum, a structure attached to the bottom of the brain that is involved in coordinating posture and balance but also in supporting some cognitive functions. Cigarette smoking, which often co-occurs with alcohol use, has also been shown to impact brain structure and function, and co-use of these substances is purported to accelerate aging of the brain. A report published in the journal Alcoholism: Clinical & Experimental Research examines neuroimaging (MRI) data from 92 people in order to further investigate the impact of smoking and alcohol status on the volume of the cerebellum and related cognitive function.
