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...

Understanding The Nose

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...

Where the nonspecific thalamus meets the prefrontal cortex Inside the brains of mice and men alike, a relatively big football-shaped region called the thalamus acts like a switchboard, providing the prefrontal cortex, the part that does abstract thinking and decision-making, with most of its information. The thalamus's responsibility even includes helping the prefrontal cortex to maintain consciousness and arousal. Essential as this "thalamocortical" partnership is, neuroscientists have...

They show how embryonic origin and timing influence cell specification and network integration The cerebral cortex of the human brain has been called "the crowning achievement of evolution." Ironically, it is so complex that even our greatest minds and most sophisticated science are only now beginning to understand how it organizes itself in early development, and how its many cell types function together as circuits. A major step toward this great goal in neuroscience has been taken by...

Brain Waves And The Neural Basis Of Consciousness
2012-11-22 07:00:49

April Flowers for redOrbit.com - Your Universe Online How our brains encode thoughts, such as perceptions and memories, at the cellular level is one of the biggest puzzles in neuroscience today. One theory suggests that ensembles of neurons represent each unique piece of information. No one knows, however, just what these ensembles look like, or how they form. A new study, published in a recent issue of Neuron, sheds light on how neural ensembles form thoughts and support the...

Brain's code for visual working memory deciphered in monkeys -- NIH-funded study The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study supported by the National Institutes of Health suggests. The more in-sync such electrical signals of neurons were in two key hubs of the circuit, the more those cells held the short-term memory of a just-seen object. Charles Gray, Ph.D., of Montana State University, Bozeman, a grantee of...

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...
