Faulty Connections In Autistic Brains
2013-06-26 09:39:07

April Flowers for redOrbit.com - Your Universe Online New light is being shed on the effects autism has on the brain by a group of researchers from San Diego State University’s Brain Development Imaging Laboratory. According to the findings, the connection between the thalamus – a deep brain structure critical to sensory and motor functions – and the brain’s outer layer known as the cerebral cortex is impaired in children with autism spectrum disorders (ASD). This first of...

3-D Roadmap Of The Human Brain
2013-06-21 06:05:12

redOrbit Staff & Wire Reports - Your Universe Online Researchers in Germany and Canada have created a spectacular 3-D digital reconstruction of a complete human brain that reveals unprecedented detail. The map, dubbed the BigBrain, has a spatial resolution just 20 microns "smaller than the size of one fine strand of hair" and represents the first time that human brain anatomy has been shown in such ultra-high resolution. Until recently, reference brains did not show much beyond...

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...

Early Differentiation Of Higher Brain Structures Affected By Competing Pathways
2013-04-26 11:36:30

Georgia Institute of Technology Sand-dwelling and rock-dwelling cichlids living in East Africa's Lake Malawi share a nearly identical genome, but have very different personalities. The territorial rock-dwellers live in communities where social interactions are important, while the sand-dwellers are itinerant and less aggressive. Those behavioral differences likely arise from a complex region of the brain known as the telencephalon, which governs communication, emotion, movement and...

Scientists Probe Source Of A Pulsing Signal In The Sleeping Brain
2013-04-18 13:35:40

Technische Universitaet Muenchen New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. For the first time, researchers have shown conclusively that slow waves start in the cerebral cortex, the part of the brain responsible for cognitive functions. They also found that such a wave...

Migraines Linked To Abnormalities In Brain Cortex
2013-03-27 08:35:24

Alan McStravick for redOrbit.com - Your Universe Online The prevailing science on the subject of migraine headaches had long recognized that certain people are simply more likely to be afflicted by this potentially debilitating condition than others. In fact, the Mayo Clinic details a handful of risk factors that can make someone more or less likely to experience migraines. Among the recognized risk factors are family history, age, gender and hormonal changes. While these and other risk...

A region of the brain known to play a key role in visual and spatial processing has a parallel function: sorting visual information into categories, according to a new study by researchers at the University of Chicago. Primates are known to have a remarkable ability to place visual stimuli into familiar and meaningful categories, such as fruit or vegetables. They can also direct their spatial attention to different locations in a scene and make spatially-targeted movements, such as...

WASHINGTON, Jan. 29, 2013 /PRNewswire-USNewswire/ -- In work supported by The ALS Association and funded through The Milton Safenowitz Post-Doctoral Fellowship Program, researchers have for the first time reprogrammed a neuron from one type into another and have done so in a living organism. The finding will help scientists better understand how to control neuronal development and may one day aid in treating diseases in which neurons die, such as amyotrophic lateral sclerosis (ALS). The study...

Understanding The Nose
2012-12-19 18:59:17

Michael Harper for redOrbit.com — Your Universe Online Science is a magnificent thing and yet, there is still so much we don´t yet understand. For instance, scientists are still working to fully understand the part of our body that resides right in front of our face. More than 100 years ago, scientists discovered a mechanism that provides feedback from our nose to our brain. Though these scientists discovered this mechanism, they weren´t yet able to fully understand how it...

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...

Brain

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
