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.
Tech Xplore / A humanoid robot's social expressiveness may backfire when it makes mistakes
For robots to be successfully deployed in real-world environments, humans should trust them enough to cooperate with them. Some roboticists have been trying to determine whether users perceive robots that exhibit socially ...
Medical Xpress / Loneliness rewires the brain to drive alcohol use, preclinical study finds
Loneliness can reprogram the brain in ways that increase alcohol consumption, according to a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies. The scientists identified, for ...
Medical Xpress / How the brain distinguishes the consequences of our own choices from events beyond our control
A study led by the University of Oxford has identified the brain mechanisms that help us work out whether the consequences we experience are caused by our own actions or by circumstances beyond our control.
