A new study of 9 and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. “White matter” describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity. The team reports its findings in the open-access journal Frontiers in Human Neuroscience.
In a new study published in The Journal of Neuroscience, researchers report that the amygdala — a part of the brain associated with decision making, memory and emotion — plays a part in telling us who to trust almost instantly.
The latest research on sports concussions in teens has been the focus of recent study.
Depression is known to be a common symptom of Parkinson’s disease, but remains untreated for many patients, according to a new study.
Following another person’s gaze can reveal a wealth of information critical to social interactions and also to safety. Gaze following typically emerges in infancy, and new research looking at preterm infants suggests that its visual experience, not maturational age, that underlies this critical ability.
fMRI scans reveal brain differences in risk-taking teens
Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development, according to a study by neuroscientists at Columbia University Medical Center (CUMC).
While much attention has focused on the link between violent video game playing and aggression among youths, a new study finds significantly increased signs of depression among preteens with high daily exposure to violent video games.
An imaging study of chronic users of codeine-containing cough syrups (CCS) has found deficits in specific regions of brain white matter and associates these changes with increased impulsivity in CCS users.
New treatments for multiple sclerosis (MS) using common anti-psychotic agents have been discovered by Victoria University of Wellington researchers.
People with schizophrenia struggle to turn goals into actions because brain structures governing desire and emotion are less active and fail to pass goal-directed messages to cortical regions affecting human decision-making, new research reveals.
