Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study by Yale researchers.
Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study published the week of Nov. 21 in the Proceedings of the National Academy of Sciences. Understanding how meditation works will aid investigation into a host of diseases, he said. (more…)
*Research is a step toward understanding cause of autism*
COLUMBIA, Mo. –The face and brain develop in coordination, with each influencing the other, beginning in the embryo and continuing through adolescence. Now, University of Missouri researchers have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children.This knowledge could help researchers understand the origins of autism.
“There is no clear answer about whether autism is caused by genetics or by environmental influences,” said Kristina Aldridge, lead author and assistant professor of anatomy in the MU School of Medicine and the Thompson Center for Autism and Neurodevelopmental Disorders. “If we can identify when these facial changes occur, we could pinpoint when autism may begin to develop in a child. Knowing that point in time could lead us to identify a genetic cause, a window of time when the embryo may be susceptible to an environmental factor, or both.” (more…)
*The 5th annual Microsoft Firenze BXT Student Innovation Competition brings together business, design and engineering students to showcase how innovation happens in the real world. This year’s finals take place this weekend on Microsoft’s Redmond campus*
REDMOND, Wash. – Feb. 4, 2011 – Midway through last year’s Microsoft Firenze BXT student innovation competition, James Liu realized something he wasn’t expecting.
Yale University researchers have found that a single molecule not only connects brain cells but also changes how we learn. The findings, reported in the December 9 issue of the journal Neuron, may help researchers discover ways to improve memory and could lead to new therapies to correct neurological disorders.
The junctions between brain cells over which nerve pulses pass — called synapses — are crucial for regulating learning and memory and how we think. Aberrations in the structure and function of synapses have been linked to mental retardation and autism, while synapses are lost in the aging brains of Alzheimer’s patients. (more…)
