Sugar makes you stupid: study shows how a high-fructose diet sabotages learning, memory
May 15, 2012
A new UCLA rat study is the first to show how a diet steadily high in fructose slows the brain, hampering memory and learning—and how omega-3 fatty acids can counteract the disruption. The peer-reviewed Journal of Physiology publishes the findings in its May 15 edition.
Changing brains for the better; article documents benefits of multiple practices
Apr 19, 2012
Practices like physical exercise, certain forms of psychological counseling, and meditation can all change brains for the better, and these changes can be measured with the tools of modern neuroscience, according to a review article now online at Nature Neuroscience.
How genes organize the surface of the brain
Mar 29, 2012
The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists. The work is published in the March 30 issue of the journal Science.
Once considered mainly ‘brain glue,’ astrocytes’ power revealed
Mar 29, 2012
A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier neurons, wields more power in the brain than has been realized, according to new research published today in Science Signaling.
Researchers wrest partial control of a memory
Mar 23, 2012
Scientists have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to weaken harmful thoughts for those with conditions such as schizophrenia and posttraumatic stress disorder.
Tracking proteins behaving badly provides insights for treatments of brain diseases
Mar 19, 2012
A research team led by the University of Melbourne has developed a novel technique that tracks diseased proteins behaving badly by forming clusters in brain diseases such as Huntington and Alzheimer disease.
