Brain Creates Personality Models To Predict Behavior
2013-03-06 06:11:02

April Flowers for redOrbit.com - Your Universe Online An international team of researchers led by Cornell University reveals that it is possible to tell who a person is thinking about by analyzing images of his or her brain. Nathan Spreng, assistant professor of human development in Cornell's College of Human Ecology, and his colleagues demonstrate that our mental models of people produce unique patterns of brain activation, which can be detected using advanced imaging techniques....

Hands Free Does Not Mean Brain Free
2013-03-01 05:11:20

redOrbit Staff & Wire Reports - Your Universe Online Making a left-hand turn at a busy intersection while talking on a hands-free cellphone could be the “most dangerous” thing we do on the road due to the high level of brain activation involved, according to a new Canadian study. Researchers tested healthy young drivers operating a novel driving simulator equipped with a steering wheel, brake pedal and accelerator inside a high-powered functional MRI. This methodology...

Evolution Gave Humans Unique Brain Structures Over Primates
2013-02-24 06:04:08

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a pair of functional networks in the human cerebral cortex that are not present in the brains of rhesus macaque monkeys, leading them to theorize that the networks were added during the evolution from ancient primates to the modern day homo sapiens. The networks were discovered by a team of researchers led by neurophysiologist Wim Vanduffel of University of Leuven and Harvard Medical School (HMS), who...

Awake craniotomy — a procedure in which the patient remains awake during brain tumor surgery in order to determine if the operation will touch on any areas that affect such abilities as speech, movement and vision — can now be done on many patients whose tumors were previously thought inoperable, or for whom surgery would have been very risky, due to the tumors´ location. This good news is due to new neuronavigation, neurosurgical, microneurosurgical and functional brain...

New study reveals how control of brain blood flow develops with age A new study by Columbia Engineering researchers finds that the infant brain does not control its blood flow in the same way as the adult brain. The paper, which the scientists say could change the way researchers study brain development in infants and children, is published in the February 18 Early Online edition of Proceedings of the National Academy of Sciences (PNAS). "The control of blood flow in the brain is very...

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...

Cognitive Benefits Of Bilingualism For The Elderly
2013-01-10 11:06:40

Connie K. Ho for redOrbit.com — Your Universe Online A recent study by researchers at the University of Kentucky College of Medicine (UKCM) found that aging adults who grew up bilingual are able to maintain better “cognitive flexibility” and more efficient use of their brains than their monolingual peers. The study, recently featured in The Journal of Neuroscience, looked at seniors who have practiced speaking two languages since childhood. The...

Watching Sesame Street Helps Children’s’ Brain Develop Intellectual Abilities
2013-01-04 11:21:14

[Watch Video: Sesame Street Helps Brain Development] Lawrence LeBlond for redOrbit.com - Your Universe Online Using brain images, researchers are gaining insight into how humans process thought during real-life experiences. The same researchers studied brain scans of children and adults while they watched Sesame Street and found that a child´s brain changes as they develop intellectual abilities like reading and math. The scientists say that the novel use of brain imaging in this...


Word of the Day
