For the first time, scientists can see pathways to stop a deadly brain cancer in its tracks. Researchers at Case Western Reserve University School of Medicine have imaged individual cancer cells and the routes they travel as the tumor spreads. http://medicalxpress.com/news/2011-08-uncovering-deadly-cancer.html Cancer Fri, 26 Aug 2011 10:38:11 EST news233573873 Seeing and exploring both are necessary for stability in a person's episodic memory when taking in a new experience, say University of Oregon researchers. http://medicalxpress.com/news/2011-08-personal-memory.html Neuroscience Mon, 22 Aug 2011 15:28:06 EST news233245674 Like explorers mapping a new planet, scientists probing the brain need every type of landmark they can get. Each mountain, river or forest helps scientists find their way through the intricacies of the human brain. http://medicalxpress.com/news/2011-08-scientists-brain-nooks-crannies.html Medical research Tue, 09 Aug 2011 17:00:14 EST news232118428 The human brain is the most complex of all organs, containing billions of neurons with their corresponding projections, all woven together in a highly complex, three-dimensional web. To date, mapping this vast network posed a practically insurmountable challenge to scientists. Now, however, a research team from the Heidelberg-based Max Planck Institute for Medical Research has developed a method for tackling the mammoth task. Using two new computer programs, KNOSSOS and RESCOP, a group of over 70 students mapped a network of more than 100 neurons – and they did so faster and more accurately than with previous methods. http://medicalxpress.com/news/2011-07-brain-connectome-.html Neuroscience Thu, 28 Jul 2011 12:58:00 EST news231076666 The human brain is adept at recognizing similar items and placing them into categories — for example, dog versus cat, or chair versus table. In a new study, MIT neuroscientists have identified the brain activity that appears to control this skill. http://medicalxpress.com/news/2011-07-brain-assigns-categories.html Neuroscience Thu, 28 Jul 2011 04:09:16 EST news231044941 Insomnia is the most prevalent sleep disorder, affecting up to 50 percent of the adult population in the United States on a weekly basis. http://medicalxpress.com/news/2011-06-forest-baptist-clinical-insomnia-technology.html Medical research Thu, 30 Jun 2011 11:39:13 EST news228652744 Neuroscientists at Georgetown University Medical Center (GUMC) have defined, for the first time, three different processing stages that a human brain needs to identify sounds such as speech — and discovered that they are the same as ones identified in non-human primates. http://medicalxpress.com/news/2011-06-components-speech-recognition-pathway-humans.html Neuroscience Wed, 22 Jun 2011 14:51:44 EST news227973087 Neurobiologists have determined the number of circuits needed to see movements. http://medicalxpress.com/news/2011-06-tracking-motion-perception.html Neuroscience Wed, 22 Jun 2011 12:37:52 EST news227965032 (Medical Xpress) -- We like to think the human brain is special, something different from other brains and information processing systems, but a Cambridge professor set out to test that assumption – by conducting a live experiment using Twitter. http://medicalxpress.com/news/2011-05-neuro-tweets-hashtagging-brain-video.html Neuroscience Mon, 09 May 2011 07:29:10 EST news224144851 The Allen Institute for Brain Science has released the world's first anatomically and genomically comprehensive human brain map, a previously unthinkable feat made possible through leading-edge technology and more than four years of rigorous studies and documentation. The unprecedented mappings are the foundation for the Allen Human Brain Atlas, an online public resource developed to advance the Institute's goal to accelerate understanding of how the human brain works and fuel new discovery among the global research community. http://medicalxpress.com/news/2011-04-allen-brain-science-comprehensive-gene.html Neuroscience Tue, 12 Apr 2011 11:43:44 EST news221827315
