Working Memory and the Brain
Visual working memory not as specialized in the brain as visual encoding, study finds. Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance [Read More]
Magic Mushrooms’ Effects Illuminated in Brain Imaging Studies
Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two studies being published in scientific journals this week [Read More]
T-rays Technology Could Help Develop Star Trek-style Hand-held Medical Scanners
Scientists have developed a new way to create Terahertz waves (T-rays) that may one day lead to biomedical detective devices similar to the ‘tricorder’ scanner used in Star Trek. Scientists have developed a new way to create electromagnetic Terahertz (THz) waves [Read More]
A Gene for Depression Localized
Psychiatric disorders can be described on many levels, the most traditional of which are subjective descriptions of the experience of being depressed and the use of rating scales that quantify depressive symptoms. Over the past two decades, research has developed other [Read More]
UT Health Researchers Link Multiple Sclerosis to Different Area of Brain
Radiology researchers at The University of Texas Health Science Center at Houston (UTHealth) have found evidence that multiple sclerosis affects an area of the brain that controls cognitive, sensory and motor functioning apart from the disabling damage caused by the [Read More]
Ready to learn? Brain Scans Can Tell You
Neuroscientists identify brain activity that predicts how well you will remember images. Our memories work better when our brains are prepared to absorb new information, according to a new study by MIT researchers. A team led by Professor John Gabrieli has shown that [Read More]
High Blood Pressure, Diabetes, Smoking and Obesity in Middle Age May Shrink Brain, Damage Thinking
A new study suggests smoking, high blood pressure, diabetes and being overweight in middle age may cause brain shrinkage and lead to cognitive problems up to a decade later. The study is published in the August 2, 2011, print issue of Neurology, the medical journal of the [Read More]
Effects of Obesity On the Brain: Sex-Related Differences in the Brain’s White Matter
Effects of obesity on the brain: first evidence of sex-related differences in the brain’s white matter structure Obesity is today one of the most prevalent medical conditions, and has a major impact on health. Recent studies have also shown a relationship between weight [Read More]
New Insight Into “Aha!” Memories
When we suddenly get the answer to a riddle or understand the solution to a problem, we can practically feel the light bulb click on in our head. But what happens after the “Aha!” moment? Why do the things we learn through sudden insight tend to stick in our memory? [Read More]
Quit Smoking Messages in the Brain
Quit smoking messages were more effective when tailored toward an individual and when that individual showed greater activity in self-related brain regions such as the dorsomedial prefrontal cortex. Using MRI, researchers compared subjects’ brain images taken during [Read More]
