fMRI Used To Unravel The Brain's Vision Secrets
2013-02-04 04:59:42

redOrbit Staff & Wire Reports - Your Universe Online The areas of the human brain responsible for our perception of shape and orientation have been discovered by researchers from a pair of UK-based universities — a discovery which they call an important advance in the understanding of how our minds process visual information. Scientists from the University of York Department of Psychology and the University of Bradford School of Optometry & Vision Science used functional...

The Impact Of fMRI Over The Past 20 Years
2013-01-17 06:07:29

Connie K. Ho for redOrbit.com — Your Universe Online A new study published in the January edition of the Perspectives of Psychological Science reveals the impact of functional magnetic resonance imaging (fMRI) over the last 20 years, and argues that there are some issues that remain unclear. To begin, fMRI has been used to evaluate real-time brain activity. The tool can determine changes in blood flow and help researchers better understand the human brain. Past studies at...

Findings also illustrate how individuals can train their brains to handle injuries more efficiently For the first time, scientists at Carnegie Mellon University's Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury. The research, published in Cerebral Cortex, shows that when one brain area loses functionality, a "back-up" team of secondary brain areas immediately activates, replacing not...

Guppy Study Reveals Costly Nature Of Having Big Brains
2013-01-04 12:00:47

Brett Smith for redOrbit.com - Your Universe Online As the most intelligent animals on the planet, we often wonder–how did we get so darn smart? While there are many hotly contested theories, a new study from researchers at Uppsala University in Sweden supports the notion that large, energy-expensive brains evolved in primates at the cost of other bodily functions, also known as the Expensive Tissue Theory. If bigger and better brains were always selected for, then every animal...

Bigger brains can make animals, well, brainier, but that boost in brain size and ability comes at a price. That's according to new evidence reported on January 3rd in Current Biology, a Cell Press publication, in which researchers artificially selected guppies for large and small brain sizes. The findings lend support to the notion that bigger brains and increased cognitive ability do go together, a topic that has been a matter of considerable debate in recent years, said Niclas Kolm of...

How The Brain Categorizes Thousands Of Objects And Actions Revealed By New Study
2012-12-19 16:52:49

Cell Press [ Watch The Video ] Humans perceive numerous categories of objects and actions, but where are these categories represented spatially in the brain? Researchers reporting in the December 20 issue of the Cell Press journal Neuron present their study that undertook the remarkable task of determining how the brain maps over a thousand object and action categories when subjects watched natural movie clips. The results demonstrate that the brain efficiently represents the diversity...

Active Lifestyle Plays A Significant Role In Keeping The Brain Healthy
2012-11-26 12:28:43

Lawrence LeBlond for redOrbit.com - Your Universe Online We all know that exercise helps keep us healthy and feeling young, but it´s not just our body that is reaping the rewards. According to researchers from UCLA, an active lifestyle also keeps our brain healthier and younger compared to our less-active peers. Lead author Cyrus Raji and colleagues set out to determine what role physical activity plays in overall health of the brain during aging. Specifically, the researchers...

Brain Waves Translated Into Music
2012-11-15 21:48:46

Brett Smith for redOrbit.com — Your Universe Online Chinese researchers at the University of Electronic Science and Technology in Chengdu, China have developed a method to transform brain waves into music that closely resembles something a human composer would write. According to their report in the open access journal PLOS ONE, they were able to use an electroencephalogram (EEG) to create the pitch and duration of a note, and functional magnetic resonance imaging (fMRI) to...

Supercomputer Simulations Of Blast Waves On The Brain Studied To Improve Helmets
2012-11-15 12:46:32

Sandia National Laboratories Researchers at Sandia National Laboratories and the University of New Mexico are comparing supercomputer simulations of blast waves on the brain with clinical studies of veterans suffering from mild traumatic brain injuries (TBIs) to help improve helmet designs. Paul Taylor and John Ludwigsen of Sandia´s Terminal Ballistics Technology Department and Corey Ford, a neurologist at UNM´s Health Sciences Center, are in the final year of a four-year...
