Physical activity promotes changes in the brain that may protect high-risk individuals against cognitive decline, including development of Alzheimer’s disease, according to a new study done at the University of Wisconsin-Milwaukee (UWM).

CLEVELAND — Coaching happens just about everywhere, and every day, with learning as the goal.
Effective coaching can lead to smoothly functioning organizations, better productivity and potentially more profit. In classrooms, better student perfo…
AUSTIN, Texas — Because of impairments in their insulin sensitivity, obese individuals demonstrate different brain responses than their normal-weight peers while completing a challenging cognitive task, according to new research by psychologists …
Researchers at the University of Illinois at Chicago are the first to use brain imaging to examine the effects of emotion on working memory function in children with pediatric bipolar disorder or attention deficit hyperactivity disorder.
The study…
Philadelphia, PA, 9 September, 2010 – There is new evidence that people can learn to control the activity of some brain regions when they get feedback signals provided by functional magnetic resonance brain imaging (fMRI).
Dr. Andrea Caria and col…
UPTON, NY — A brain-scanning study at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, conducted with collaborators from Stony Brook University, reveals that an oral dose of methylphenidate, commonly known as Ritalin, improve…
Depression is actually defined by specific clinical symptoms such as sadness, difficulty to experience pleasure, sleep problems etc., present for at least two weeks, with impairment of psychosocial functioning. These symptoms guide the physician to …
A child falls from his bicycle and his father winces. A bride says “I do” and the maid of honor grins from ear to ear. A mother frowns with displeasure and her infant son frowns back. UCLA neuroscientists using functional magnetic resonance imaging (fMRI) are the first to demonstrate that empathetic action, such as mirroring facial expressions, triggers far greater activity in the emotion centers of the brain than mere observation.
New findings by researchers at the University of California, Berkeley, could significantly improve the resolution of scans from functional magnetic resonance imaging, one of neuroscience’s most powerful research tools to date. Functional MRI (fMRI) is a non-invasive procedure that detects increased levels of blood flow into certain areas of the brain to infer neural activity. But in a study published Feb. 14 in the journal Science, researchers from UC Berkeley’s Group in Vision Science show that an initial decrease in oxygen levels is an earlier and more spatially precise signal of nerve cell activity.
The experiences of millions of people have proved that antidepressants work, but only with the advent of sophisticated imaging technology have scientists begun to learn exactly how the medications affect brain structures and circuits to bring relief from depression. Researchers at UW-Madison and UW Medical School recently added important new information to the growing body of knowledge. For the first time, they used functional magnetic resonance imaging (fMRI)–technology that provides a view of the brain as it is working–to see what changes occur over time during antidepressant treatment while patients experience negative and positive emotions.
