Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity What if experts could dig into the brain, like archaeologists, and uncover the history of past experiences? This ability might reveal what makes each of us a unique individual, and it could enable the objective diagnosis of a wide range of neuropsychological diseases. New research at the Weizmann Institute hints that such a scenario is within the realm...

Researchers Don't Ask How You Feel, They Use Brain Activity Instead
2013-06-20 14:48:33

[ Watch the Video: Identifying Emotions Using Brain Activity ] Brett Smith for redOrbit.com - Your Universe Online Instead of asking someone how they feel, a group of researchers at Carnegie Mellon has found a way to identify a person's emotion based on brain activity, according to a new report in the journal PLoS ONE. Previous efforts to view emotions through brain imaging have been hampered by study participants' reluctance to report emotion or emotional responses that are not...

2013-06-18 13:09:41

University of Washington For less than $100, University of Washington researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write. The device and research using it to study the brain patterns of children will be presented June 18 at the Organization for Human Brain Mapping meeting in Seattle. A paper describing the tool, developed by the UW´s Center on Human Development and...

Blood vessels within a sensory area of the mammalian brain loop and connect in unexpected ways, a new map has revealed. The study, published June 9 in the early online edition of Nature Neuroscience, describes vascular architecture within a well-known region of the cerebral cortex and explores what that structure means for functional imaging of the brain and the onset of a kind of dementia. David Kleinfeld, professor of physics and neurobiology at the University of California, San...

Researchers Create Mind-Controlled Flying Robot

April Flowers for redOrbit.com — Your Universe Online A new, non-invasive system that allows people to control a flying robot using only their mind has been developed by researchers at the University of Minnesota, according to a study published in the Journal of Neural Engineering. Although it sounds like fun and games, the study´s findings have implications for helping people who are paralyzed or have neurodegenerative diseases.

Scientists Look At How The Brain Compensates For Speed
2013-05-08 18:47:22

Michael Harper for redOrbit.com — Your Universe Online Researchers from the University of California in Berkeley have finally pinpointed the area of the brain responsible for not only seeing fast-moving objects, but responding to them as well. This development explains why athletes are able to react and respond to balls traveling at speeds upwards of 100 miles an hour. According to this research, our brains are capable of “pushing” fast moving objects, so we perceive...

UC Berkeley study shows how we refocus to track down a human, animal or thing A contact lens on the bathroom floor, an escaped hamster in the backyard, a car key in a bed of gravel: How are we able to focus so sharply to find that proverbial needle in a haystack? Scientists at the University of California, Berkeley, have discovered that when we embark on a targeted search, various visual and non-visual regions of the brain mobilize to track down a person, animal or thing. That means...

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute (ORI) senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model. The results indicated that elevated responsivity of reward regions in the brain increased the risk for future substance use, which has never been...
