Om My! Meditation Changes Brain Structure

Brain scans indicate permanent, positive development

(Newser) - This might already be obvious to enlightened souls, but researchers are discovering that meditation may permanently change the physical structure of the brain.

Obesity May Shrink Your Brain

Study finds cognitive regions smaller in obese elderly

(Newser) - Important cognitive brain regions are smaller in older obese people than fit ones, scientists have found. Shrinking brains are tied to dementia, so the discovery fuels the notion that obesity can raise the risk of the cognitive disorder, New Scientist reports. In a review of 94 brain scans, subjects with... More »

New Autism Research Tests Brain's 'Reflexes'

(Newser) - Scientists are taking a new approach to autism research using magnetic field generators that test the brain’s reflexes, the Boston Globe reports. Much like tapping a patient on the knee to gauge a physical reaction, trans-cranial magnetic stimulation triggers activity in specific areas of the brain through a charged... More »

Scientists Read Subjects' Location From Brain Scans

(Newser) - Decoding part of the complex system used by the brain to store memories has allowed scientists to determine a person’s location by looking at brain scans, Wired reports. A study took images of the hippocampus—the part responsible for spatial relationship and short-term memories—as individuals navigated a virtual-reality... More »

Brain Scans May Predict Alzheimer's

(Newser) - Researchers have discovered a new link between Alzheimer’s disease and mild cognitive impairment, a condition that often leads to the brain disorder, CNN reports.
