Normal brain growth curves for children developed

Based on more than a thousand brain scans, the findings have implications for diagnosing and treating childhood brain disorders, infections and injuries.

Coupled brain activity, cerebrospinal fluid flow could indicate Alzheimer's risk

Penn State researchers may have discovered a potential marker to clinically evaluate patients’ risk for Alzheimer’s disease through non-invasive imaging tests, according to a study published in PLOS Biology. The finding may have implications for diagnosis and treatment of the disease that results in significant cognitive decline, the researchers said.

Infants exposed to second-hand smoke may develop behavior problems later in life

When parents think of baby-proofing, they may think of baby gates and outlet covers, but there might be something less obvious to consider: whether previous occupants of their home were smokers. According to a National Institutes of Health-funded study by researchers at Penn State and the University of North Carolina at Chapel Hill (UNC), babies can be exposed to nicotine left behind in the home.

Increased blood flow during sleep tied to critical brain function

Our brains experience significant changes in blood flow and neural activity during sleep, according to Penn State researchers. Such changes may help to clean out metabolic brain waste that builds up during the day.

Researchers will evaluate the results of two self-administered, scratch-and-sniff smell tests for COVID-19. The first involves asking users to identify odors such as smoke, strawberry, chocolate and onions, while the second is designed to reveal a participant’s sensitivity to different concentrations of the same odor

Researchers investigate an at-home 'scratch-and-sniff' test for COVID-19

A self-administered "scratch-and-sniff" test for COVID-19 may be around the corner, according to researchers at Penn State, the University of Florida, and Arizona State University.

Some neurons target tiny cerebral blood vessel dilation

Neurons control blood flow in tiny vessels in the brain, but researchers know little about this relationship. Now a team of Penn State engineers has found a connection between nitric oxide expressing neurons and changes in arterial diameters in mice, which may shed light on brain function and aging.

The Collaborative Informatics and Neuroimaging Suite Toolkit for Anonymous Computation (COINSTAC) platform is a peer to peer system that operates to make data available for analysis, while protecting anonymity and privacy. COINSTAC makes possible virtual sharing and analyses with identified collaborators in the absence of moving any data. Collaboration and data sharing are done through forming temporary virtual clusters of studies performing automatically generated local computation on their respective data and aggregating statistics.

Psychology professor receives grant to 'harmonize' brain injury data

A provisional grant from the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, will help Penn State professor of psychology, Frank Hillary, and 37 co-investigators from all over the world promote brain injury data sharing worldwide in the hopes of advancing science and improving patient outcomes.

Making Connections: Psychologist explores the neuroscience of creativity

Is there anything more mysterious — or human — than the creative impulse? Whatever the field of endeavor: music, art, science, business… What accounts for the inspired burst of innovation? The spark that flits to flame and lights the way to something entirely new?

Researchers deconstruct the 'biological clock' that regulates birdsong

The precise timing of a bird's complex song is driven in part by the often-ignored “wires” connecting neurons in the bird's brain, according to a new study. A team of researchers from Penn State and NYU Langone Health has deconstructed an important “biological clock” that regulates birdsong and other behaviors, leading to new ways of thinking about the function of neuronal networks.

Bacteria virus combo may be cause of neonatal brain infections in Uganda

A newly identified bacteria and a common virus may be the underlying cause of infection-induced hydrocephalus in Uganda, according to an international team of researchers.
