The brain is unique in that it houses our cognitive and emotional capacities in the form of the mind. It is a 'cognitive' organ that hungers for stimulation from new experiences and challenges. Many brain fitness programs strive to satisfy this need.<br /><br />Yet the brain is also a physical organ that plays by many of the same rules as the heart, lungs, liver and kidneys. To stay healthy and perform optimally it requires quality nutrition, physical activity and optimal sleep. The brain, especially, relies on a healthy vascular system to efficiently deliver oxygen and key nutrients and remove waste. In fact, the brain uses approximately 20% of the oxygen we breathe to satisfy its high-energy demands. Given that the brain only weighs about 2% of the body, we can consider it an energy hog and we must cater to its needs very carefully.<br /><br />Nutrients play key roles in brain function. Several have shown efficacy in clinical trials treating cases of mood disorders, cognitive decline and of course benefiting the physical health of the brain. Nutrients are both the raw materials employed in creating new neural connections and important components in regulating the activity of genes involved in these processes. Specific nutrients involved in mitochondrial efficiency, the energy factories of brain and body cells, are particularly important for many aspects of brain function. Other nutrients are involved in the inner workings of neuronal membranes, responsible for ensuring that electrochemical signals, which make up our thoughts, transmit efficiently and reliably.<br /><br />Finally, antioxidants, important throughout the body, are especially important in the brain due to its high energy production rates and concurrent high capacity for free radical leakage. Keeping this in mind, it is readily apparent that nutrition provides the building blocks for our brain's structure and function, and therefore cannot be ignored.<br /><br />Exercise is a clearly established component for promoting brain health as well. No longer can we think that the brain is completely separate from the brawn. Human studies have shown the value of exercise in controlling stress and maintaining positive mood states; in improving cognitive function, including performance on memory and executive tasks; and in improving the brain's two-way communication streams with the rest of the body. Some of these benefits are likely due to the positive effects of exercise on neurovascular health, which parallel cardiovascular health. Other benefits seem due to increased grey matter in 'front office' functions of the cortex; and neuronal birth, or neurogenesis, in the hippocampus, a brain region that controls aspects of memory and mood regulation.<br /><br />Whatever the mechanism, giving your body a workout will produce substantial benefits in terms of brain health. Remember, a body in motion tends to stay in motion, and your brain and body will be together your whole life.<br /><br /><strong>Read More Here:</strong> <a href="http://www.sharpbrains.com/"><strong>http://www.sharpbrains.com/</strong></a></div><br /><div align="justify"></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6748141362683220759.post-83551167189986096352008-09-25T12:04:00.000-07:002008-09-25T12:09:40.221-07:00Fluid Intelligence and the Prefrontal Cortex<div align="justify"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQ2d2IzBSDE2IWJa8h103wk-KRmzwBlSDoJP8k1ldO5f9jHP1rTGi1VzGviCtrseXC277oO1mP0cx_DFtphqJyUQ6GrVzUhdRROHtwM4IMzZs65QLZxG4Z_CFb-PfK8l1NfNC6Gq9pHfLh/s1600-h/prefront.jpg"><img id="BLOGGER_PHOTO_ID_5250038019886253810" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQ2d2IzBSDE2IWJa8h103wk-KRmzwBlSDoJP8k1ldO5f9jHP1rTGi1VzGviCtrseXC277oO1mP0cx_DFtphqJyUQ6GrVzUhdRROHtwM4IMzZs65QLZxG4Z_CFb-PfK8l1NfNC6Gq9pHfLh/s200/prefront.jpg" border="0" /></a> <span style="font-size:130%;"><strong><span style="color:#ff6600;">The Positive Manifold: Reactive Control in Fluid Intelligence</span></strong>?<br /></span><strong>by Chris Chatham</strong><br /><br />What <strong>neural mechanisms</strong> underlie "<strong>fluid intelligence</strong>," the ability to reason and solve novel problems?

Its not easy for anyone," said Jeremy Gray, assistant professor of psychology and co-author of the study.

Roy, Ph.D., C.Psych.<br /><span style="font-size:85%;">Director of the Centre for Habilitation Education and Research</span></strong><br /></div><div align="justify"><br />Injuries involving some type of blow to the head are among the most common in our society. Some 700,000 people in North America suffer traumatic head injuries each year, and between 70,000 and 90,000 are left permanently disabled. Head injuries can range from relatively minor damage to the scalp and face such as lacerations, abrasions and bruising to more serious consequences involving damage to the brain. While traumatic brain injury occurs much less frequently, it is important to know how it is identified and what to do for the person.<br /><br />Loss of consciousness, even for a very brief period, is one of the clearest indications that the brain may have been affected by a blow to the head. A confusional state involving uncertainty about time, date, and location and/or a period of memory loss for the events surrounding the head injury are also indicators of trauma to the brain. Any of these symptoms following a blow to the head should be taken seriously.<br /><br />With the most severe symptoms, loss of consciousness for more than a few minutes, the person should receive immediate medical attention. With less severe symptoms the person should be watched for a period of several hours after the head trauma. The person's state of consciousness, orientation to time and place and immediate memory function (e.g., remembering a series of four numbers) should be evaluated periodically during this time. Any evidence of deterioration may be a sign of the delayed effects of brain injury due to swelling or internal bleeding and require that the person receive medical attention as soon as possible. Some appreciation for how and why these symptoms arise will provide insight into why even a seemingly mild blow to the head may have very serious and potentially life-threatening consequences.<br /><br />The effects of a blow to the head on brain function arise from the structural characteristics of the skull and the brain and the direction and size of the forces acting on the head. The brain, a rather soft tissue with the consistency somewhere between egg white and jello, is covered by three membrane layers. The outer-most layer, called the dura mater, is connected to the inside of the skull at various suture points which serve to suspend the brain within the skull. The brain sits atop the brain stem, an extension of the spinal cord which passes out the base of the skull through a hole called the foramen magnum. Brain injuries arise from three characteristics of this brain-skull anatomy: the rigidity and internal contours of the skull, the incompressibility of brain tissue and the susceptibility of the brain to shearing forces.<br /><br /></div><div align="center"><strong></strong></div><div align="center"><strong>Read More: <a href="http://bstr301.biostr.washington.edu/html/special_information.html">Here</a></strong> </div>Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-6748141362683220759.post-68938887628488382852007-11-18T22:49:00.001-08:002007-11-18T22:49:57.428-08:00Research Shows The Brain's Processing Speed Is Significantly Faster Than Real TimeScientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. <br />http://www.medicalnewstoday.com/articles/89079.phpUnknownnoreply@blogger.com0tag:blogger.com,1999:blog-6748141362683220759.post-56154171498939593992007-10-24T09:50:00.000-07:002007-10-24T09:56:23.698-07:00Ramachandran Talk<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="432" height="285" id="VE_Player" align="middle"><param name="movie" value="http://static.videoegg.com/ted/flash/loader.swf"><PARAM NAME="FlashVars" VALUE="bgColor=FFFFFF&file=http://static.videoegg.com/ted/movies/VILAYANURRAMACHANDRAN-2007_high.flv&autoPlay=false&fullscreenURL=http://static.videoegg.com/ted/flash/fullscreen.html&forcePlay=false&logo=&allowFullscreen=true"><param name="quality" value="high"><param name="allowScriptAccess" value="always"><param name="bgcolor" value="#FFFFFF"><param name="scale" value="noscale"><param name="wmode" value="window"><embed src="http://static.videoegg.com/ted/flash/loader.swf" FlashVars="bgColor=FFFFFF&file=http://static.videoegg.com/ted/movies/VILAYANURRAMACHANDRAN-2007_high.flv&autoPlay=false&fullscreenURL=http://static.videoegg.com/ted/flash/fullscreen.html&forcePlay=false&logo=&allowFullscreen=true" quality="high" allowScriptAccess="always" bgcolor="#FFFFFF" scale="noscale" wmode="window" width="432" height="285" name="VE_Player" align="middle" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"></object> <br /><br />In this wide-ranging talk, Vilayanur Ramachandran explores how brain damage can reveal the connection between the internal structures of the brain and the corresponding functions of the mind. He talks about phantom limb pain, synesthesia (when people hear color or smell sounds), and the Capgras delusion, when brain-damaged people believe their closest friends and family have been replaced with imposters.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6748141362683220759.post-52828913502799483852007-09-11T11:19:00.000-07:002007-12-19T11:03:52.570-08:00The Political Brain<strong>Study finds left-wing brain, right-wing brain</strong><br /><br /><em>By Denise Gellene -Los Angeles Times Staff Writer <br />September 10, 2007</em><br /><br />Even in humdrum nonpolitical decisions, liberals and conservatives literally think differently, researchers show.<br /><br />Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work.<br /><br />In a simple experiment reported todayin the journal Nature Neuroscience, scientists at New York University and UCLA show that political orientation is related to differences in how the brain processes information. <strong><blockquote>READ MORE: <a href="http://www.latimes.com/news/science/la-sci-politics10sep10,0,5982337.story?coll=la-home-center"><strong>HERE</strong></a></blockquote></strong>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6748141362683220759.post-70666614279856458322007-08-27T16:17:00.000-07:002007-09-11T11:28:34.736-07:00The Brain: What is it Good For?<strong>A Brief History of the Brain</strong><br /><br />-evolution<br />-anatomy<br />-etc<br /><br /><strong>The Human Bodymind </strong>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6748141362683220759.post-47094129619937855342007-08-22T11:03:00.000-07:002008-03-02T22:17:52.636-08:00About Us_The Brain BlogCollecting information for anyone interested...
