Medical Xpress / Autism-risk mutations reveal two opposing patterns of brain gene activity
Autism spectrum disorder (ASD) is associated with more than 1,200 risk genes, raising a fundamental question: Do these diverse genetic changes affect the brain in entirely different ways, or do they converge on shared biological ...
Medical Xpress / Eye-blink rate offers a window into executive function and prefrontal development in early childhood
Executive function encompasses a suite of cognitive processes that enable individuals to regulate their behavior, thoughts and emotions. These skills are essential for tasks such as following instructions, controlling impulses ...
Medical Xpress / One good night's sleep reduces fatigue in hockey players
Could the secret to bouncing back after a grueling practice be as simple as sleeping just a little bit longer for one night?
Medical Xpress / How changes in prefrontal brain activity can impair the ability to change behavior
A new study has revealed how both reduced neural activity and reduced control over neural activity in the brain's prefrontal area can disrupt the ability to adapt behavior when circumstances change.
Medical Xpress / How the brain keeps its options straight at decision time
A new study by neuroscientists at MIT's Picower Institute for Learning and Memory shows how the brain encodes information throughout the decision-making process to keep options clearly in mind and ensure that chosen and unchosen ...
Medical Xpress / How the brain responds to positive emotions is key to resilience after trauma, WTC responder research shows
New research has found that how the brain responds to anticipated rewards plays a key role in building psychological resilience after a traumatic experience. The findings from the new study among 9/11 responders, appearing ...
Phys.org / A 'wholistic' view of cellular communication across an entire animal
It can't be heard, but different parts of the human body are in constant conversation, communicating to keep the entire system running efficiently. For biologists, being able to listen in on this discussion is a long-sought-after ...
Medical Xpress / Can society's emotional climate be reflected in individual brain function?
For years, I have been interested in disorders in which patients experience very real symptoms even though conventional brain imaging may look normal. Molecular imaging has taught me a simple lesson: what is invisible anatomically ...
Medical Xpress / Cerebroid study hints at how maternal inflammation may influence fetal brain development
Past studies suggest that a mother-to-be's heightened immune responses during pregnancy are linked to a higher risk of conditions affecting their offspring's brain development. While this association is well documented, the ...
Medical Xpress / Break a sweat, hear more? Early results point to a surprising link between fitness and speech perception
It's easy to take hearing for granted.
Medical Xpress / Gut bacteria linked to key brain chemicals in first-of-its-kind human study
The neuroactive potential of bacteria living in the human gut is associated with levels of key chemicals in the brain, according to a new study published in Molecular Psychiatry. The research team from the University of Surrey ...
Medical Xpress / The benefits of slow running
A growing body of evidence shows that exercise improves mood and cognitive function. However, much of this evidence comes from cycling, which allows researchers to precisely control exercise intensity in the laboratory.
