Ultrasound Enhances Sensory Perception
2014-01-13 04:29:48

redOrbit Staff & Wire Reports - Your Universe Online Ultrasound, which is used by creatures such as bats and whales as a type of sensory guidance system, can also boost sensory perception in humans by modulating brain activity, according to new research appearing in Sunday’s online edition of Nature Neuroscience. In the paper, scientists from the Virginia Tech Carilion Research Institute report that low-intensity ultrasound focused on the transcranial region of the brain can...

Contextual Information Can Trip Up The Brain On Even The Simplest Logic Problems
2013-12-21 04:59:25

redOrbit Staff & Wire Reports - Your Universe Online If the human brain is comparable to a computer, why does it so often make mistakes that its electronic counterpart does not? New research suggests it all has to do with how various problems are presented. Scientists typically like to make this comparison because both the human brain and a computer typically follow a set of rules in which to make decisions, communicate and perform other tasks. However, University of...

Anyone who has tried to learn a second language knows how difficult it is to absorb new words and use them to accurately express ideas in a completely new cultural format. Now, research into some of the fundamental ways the brain accepts information and tags it could lead to new, more effective ways for people to learn a second language. Tests have shown that the human brain uses the same neuron system to see an action and to understand an action described in language. Researchers at...

Poverty may have direct implications for important, early steps in the development of the brain, saddling children of low-income families with slower rates of growth in two key brain structures, according to researchers from the University of Wisconsin–Madison. By age 4, children in families living with incomes under 200 percent of the federal poverty line have less gray matter — brain tissue critical for processing of information and execution of actions — than kids growing up in...

Male Female Brains Complimentary

redOrbit Staff & Wire Reports - Your Universe Online Men and women have ‘striking’ differences in their neural wiring that might explain some of the behavioral differences between the two sexes, according to a study published Monday in the Proceedings of National Academy of Sciences. The study was one of the largest to date to create to compare the connectomes, neural maps of the brain, of men and women. The results revealed that men have far greater neural connectivity from...

Researchers look to armadillos, fruit flies, nematodes, and other species to understand human brain function and vision loss Research released today reveals a new model for a genetic eye disease, and shows how animal models — from fruit flies to armadillos and monkeys — can yield valuable information about the human brain. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain...

UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness. Their research, published Oct. 17 in the online journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness. "In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover...

A new study has discovered profound abnormalities in brain activity in a group of retired American football players. Although the former players in the study were not diagnosed with any neurological condition, brain imaging tests revealed unusual activity that correlated with how many times they had left the field with a head injury during their careers. Previous research has found that former American football players experience higher rates of neurodegenerative diseases such as...

In a breakthrough for understanding brain evolution, neuroscientists have shown that differences between primate brains - from the tiny marmoset to human – can be largely explained as consequences of the same genetic program. In research published in the Journal of Neuroscience, Professor Marcello Rosa and his team at Monash University's School of Biomedical Sciences and colleagues at Universidade Federal do Rio de Janeiro, in Brazil, used computer modelling to demonstrate that the...

Chronic Dizziness May Be Helped By Magnetic Stimulation
2013-10-09 04:55:36

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Johns Hopkins University School of Medicine believe that they have located a specific site in the human brain that could be one of the sources of dizziness and spatial disorientation. While dizziness can also be linked to damage to the inner ear, or to other senses such as vision, neurology instructor Dr. Amir Kheradmand and his colleagues report that they have discovered a region of the brain that plays a...
