Research conducted by Maria Ercsey-Ravasz and Zoltan Toroczkai of the University of Notre Dame's Interdisciplinary Center for Network Science and Applications (iCeNSA), along with the Department of Physics and a group of neuroanatomists in France, has revealed previously unknown information about the primate brain. http://medicalxpress.com/news/2011-07-reveals-brain-network.html Neuroscience Wed, 13 Jul 2011 16:26:46 EST news229793151 As any student who's had to study for multiple exams can tell you, trying to learn two different sets of facts one after another is challenging. As you study for the physics exam, almost inevitably some of the information for the history exam is forgotten. It's been widely believed that this interference between memories develops because the brain simply doesn't have the capacity necessary to process both memories in quick succession. But is this truly the case? http://medicalxpress.com/news/2011-07-memory-.html Neuroscience Fri, 08 Jul 2011 13:36:11 EST news229350874 (PhysOrg.com) -- Bringing the real world into the brain scanner, researchers at The University of Western Ontario from The Centre for Brain and Mind can now determine the action a person was planning, mere moments before that action is actually executed. http://medicalxpress.com/news/2011-06-future-actions-human-brain.html Neuroscience Wed, 29 Jun 2011 15:02:12 EST news228578476 Neural and biochemical processes that are affected by the loss of olfactory sensory perception are now being explored. These studies provide insight into the effects of the loss of smell on corresponding relevant brain areas. One such project, conducted with support from the Austrian Science Fund FWF, is studying the reasons behind this illness that, surprisingly, affects many people. In particular, the processes in individuals who learn to smell again after having lost this ability are being examined. http://medicalxpress.com/news/2011-06-senseless-brain-relearning.html Neuroscience Wed, 29 Jun 2011 13:26:48 EST news228572793 In a novel imaging study of sleeping toddlers, scientists at the University of California, San Diego Autism Center of Excellence report that a diminished ability of a young brain's hemispheres to "sync" with one another could be a powerful, new biological marker of autism, one that might enable an autism diagnosis at a very young age. http://medicalxpress.com/news/2011-06-weaker-brain-sync-early-autism.html Neuroscience Wed, 22 Jun 2011 12:35:12 EST news227964900 Scientists have developed a way to turn memories on and off -- literally with the flip of a switch. http://medicalxpress.com/news/2011-06-memory-brains.html Neuroscience Fri, 17 Jun 2011 03:46:53 EST news227501202 (PhysOrg.com) -- Cornell researchers have identified regions of a fish brain that reveal the basic circuitry for how all vertebrates, including humans, generate sound used for social communication. http://medicalxpress.com/news/2011-06-wired-small-fish-brain-people.html Neuroscience Tue, 14 Jun 2011 11:47:53 EST news227270860 A brain imaging study suggests that men with a history of violent behavior may have greater gray matter volume in certain brain areas, whereas men with a history of substance use disorders may have reduced gray matter volume in other brain areas, according to a report published online today by the Archives of General Psychiatry. http://medicalxpress.com/news/2011-06-brain-scans-violent-behavior.html Psychology & Psychiatry Mon, 06 Jun 2011 16:40:01 EST news226596548 Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face. http://medicalxpress.com/news/2011-05-uncover-brain.html Neuroscience Tue, 31 May 2011 11:46:36 EST news226061173 A stroke is sudden brain injury caused by a sudden vascular (blood vessel) compromise. There are two major types of strokes. An ischemic stroke occurs when blood flow to a part of the brain is blocked by clot or other debris. This is the most common type, comprising approximately 85 percent of all strokes. The other type, hemorrhagic stroke, occurs when a blood vessel or aneurysm ruptures and blood spreads in and around the brain. Strokes can be mild, or can be quite disabling, even fatal, depending on the brain area involved and the type of stroke. http://medicalxpress.com/news/2011-05-medical-minute-awareness.html Cardiology Mon, 30 May 2011 10:22:49 EST news225969669 For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain. http://medicalxpress.com/news/2011-05-autism-molecular-brain.html Genetics Wed, 25 May 2011 13:00:03 EST news225546859 Understanding the actions of other people can be difficult for those with schizophrenia. Vanderbilt University researchers have discovered that impairments in a brain area involved in perception of social stimuli may be partly responsible for this difficulty. http://medicalxpress.com/news/2011-05-people-schizophrenia-social-cues.html Psychology & Psychiatry Tue, 24 May 2011 15:48:04 EST news225470872 A new study by motor control and psychology researchers at Indiana University suggests that postural control problems may be a core feature of bipolar disorder, not just a random symptom, and can provide insights both into areas of the brain affected by the psychiatric disorder and new potential targets for treatment. http://medicalxpress.com/news/2011-05-bipolar-disorder-mind-body-treatment.html Psychology & Psychiatry Tue, 24 May 2011 12:04:16 EST news225457425 Biologists at UC San Diego have discovered that electrical oscillations in the brain, long thought to play a role in organizing cognitive functions such as memory, are critically important for the brain to store the information that allows us to navigate through our physical environment. http://medicalxpress.com/news/2011-04-electrical-oscillations-critical-spatial-memories.html Neuroscience Thu, 28 Apr 2011 14:00:10 EST news223216019
