Expectations and biases play a large role in our enjoyment of experiences such as art and wine. Now, researchers at the University of Arkansas, Arizona State University and the University of Connecticut have found that simply being told that a performer is a professional or a student changes the way the brain responds to music, and overcoming this bias takes a deliberate effort. The results will be published in Scientific Reports on April 18.
Frequent cannabis use by adolescents and young adults was associated with small reductions in cognitive function that appeared to diminish with abstinence over time.
New research using manipulated audio clips from NPR's Science Friday and YouTube videos of academic presentations indicates that poor audio quality can create distrust -- in both the information and the source, while high audio quality strengthens their credibility.
Shortly after they turn 1, most babies begin to help others, whether by handing their mother an object out of her reach or giving a sibling a toy that has fallen. Researchers have long studied how this helping behavior develops, but why it develops has been examined less. A new study looked at the role of imitation to find that when 16-month-olds observe others' helping behavior, they're more likely to be helpful themselves.
A Portland State University research team studying concussion has published an interactive diagram showing the many facets of mild traumatic brain injury (TBI) -- from sleep problems to mood disorders to the increased danger of dementia -- and how they connect with and affect each other.
Researchers at OHSU in Portland, Ore., have identified a new molecule within the brain's white matter that blocks the organ's ability to repair itself following injury. By preventing the production of this molecule, it is possible to create an effective pathway that allows the brain to continue its regenerative process. This may help to limit long-term physical and mental disability associated with devastating neurological conditions.
A newly published observational study from the Regenstrief Institute and Indiana University has found that increased levels of education, particularly for those who grew up in low-income rural areas, was significantly associated with the decrease in the risk of dementia and Alzheimer's disease in older African-Americans previously reported by the same research group.
Neurobiology researchers have identified a pathway in brain circuitry that, when stimulated, leads to 'antidepressive' behavior in animals. If such brain stimulation proves to have similar effects in people, it may eventually lead to a novel treatment for depression.
Latest research combining social and political surveys with objective cognitive testing suggests that 'cognitive flexibility' contributes to formation of ideology. Study finds correlations between cognitive thinking styles and support for Brexit.
The brain continues to put up a fight even as neurodegenerative diseases like dementia damage certain areas and functions. In fact, recent findings in a Baycrest-University of Arizona study suggest that one method the brain uses to counter these diseases is the reassigning of tasks to different regions.
