Some Fears May Be Eliminated Just By Going To Sleep
2013-09-23 09:25:43

[ Watch the Video: Never Fear! Just Sleep On It! ] Michael Harper for redOrbit.com - Your Universe Online New research has shown some fears could be unlearned while a person sleeps. Using specific odors, such as woody or floral scents, scientists were able to reduce the reactions of subjects who were trained to fear a pair of faces prior to the study. Going forward, the researchers say this new technique could be used to treat people who suffer from post-traumatic stress disorder...

Neurofeedback Can Enhance The Brain's Signal-to-noise Ratio

April Flowers for redOrbit.com - Your Universe Online As a needle sweeps across the grooves of a worn vinyl record, it carries the distinct sounds of hisses, scratches and even the echo of skips. For many years, however, if someone yearned to hear Frank Sinatra sing "Fly Me to the Moon," they were able to listen to his crooning baritone with technical clarity, courtesy of the increased signal-to-noise ratio of digital re-masterings. Recent advances in neurofeedback techniques have made...

Where Imagination Lives In The Brain
2013-09-17 04:41:12

redOrbit Staff & Wire Reports - Your Universe Online While both philosophers and scientists have searched for ages for the biological source of the human imagination, the authors of a paper appearing in this week’s edition of Proceedings of the National Academy of Sciences report that they have located it in the human brain. In the study, lead author Alex Schlegel, a graduate student in the Dartmouth University Department of Psychological and Brain Sciences, and colleagues report...

For the first time, researchers have documented irregular brain activity within the first 24 hours of a concussive injury, as well as an increased level of brain activity weeks later—suggesting that the brain may compensate for the injury during the recovery time. The findings are published in the September issue of the Journal of the International Neuropsychological Society. Thomas Hammeke, PhD, professor of psychiatry and behavioral medicine at the Medical College of Wisconsin, is...

A boost in the speed of brain scans is unveiling new insights into how brain regions work with each other in cooperative groups called networks. Scientists at Washington University School of Medicine in St. Louis and the Institute of Technology and Advanced Biomedical Imaging at the University of Chieti, Italy, used the quicker scans to track brain activity in volunteers at rest and while they watched a movie. “Brain activity occurs in waves that repeat as slowly as...

Hot Flashes In Menopause Have Neural Origins
2013-07-16 05:05:07

April Flowers for redOrbit.com - Your Universe Online For the first time in years, neuroscientists from Wayne State University School of Medicine have provided novel insights into the neural origins of hot flashes in menopausal women. The study, published in Cerebral Cortex, might inform and eventually lead to new treatments for women experiencing the sudden but temporary episodes of body warmth, flushing and sweating. "The idea of understanding brain responses during thermoregulatory...

Our Brains Act As Information DJs
2013-07-06 05:34:27

April Flowers for redOrbit.com - Your Universe Online Long before the advent of the internet, scientists were trying to understand how ideas spread. Today, the questions include "what messages will go viral on social media?" and "can this be predicted?" A new study, led by UCLA psychologists, has taken a significant step towards answering these questions. The research team has identified, for the first time, the brain regions associated with the successful spread of ideas, often called...

Researchers Take A Look Inside The Mind Of A Child
2013-06-28 08:16:07

April Flowers for redOrbit.com - Your Universe Online There is an intense look of concentration that is nearly universal to young children when their minds are hard at work. Despite recognizing the look, however, adults are never really sure what the children are thinking. A new study, led by psychologists at the University of Iowa, has used optical neuroimaging to peer inside the brain, in a first-ever attempt to quantify how much 3- and 4-year-old children are grasping when they...

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...
