When they use electrodes to record the activity patterns of individual neurons, the patterns often appear chaotic and difficult to interpret. http://medicalxpress.com/news/2013-05-clouds.html Neuroscience Tue, 21 May 2013 07:52:31 EST news288341519 (Medical Xpress)—Wake Forest University's Sean Hannah and a team of researchers have found measuring activity in the prefrontal cortex of the brain can help assess that person's potential for leadership –which could have a big impact on how future leaders are tested and trained. http://medicalxpress.com/news/2013-04-professor-neuroscience-insights-brains-complex.html Neuroscience Tue, 30 Apr 2013 06:10:01 EST news286520317 A multicenter study led by scientists at the University of Pittsburgh School of Medicine shows that mild traumatic brain injury after blast exposure produces inflammation, oxidative stress and gene activation patterns akin to disorders of memory processing such as Alzheimer's disease. Their findings were recently reported in the online version of the Journal of Neurotrauma. http://medicalxpress.com/news/2013-04-mild-blast-injury-molecular-brain.html Neuroscience Wed, 24 Apr 2013 10:55:08 EST news286019674 (HealthDay)—Talk about mind reading. Researchers have discovered a potential way to decode your dreams, predicting the content of the visual imagery you've experienced on the basis of neural activity recorded during sleep. http://medicalxpress.com/news/2013-04-scientists-peek.html Neuroscience Thu, 04 Apr 2013 15:56:34 EST news284309783 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. http://medicalxpress.com/news/2013-03-region-functions-brain-cells-multitasking.html Neuroscience Wed, 06 Mar 2013 12:00:01 EST news281792565 Scientists from the University of Leicester have hit upon unique forms of spinal nerve activity that shape output of nerve cell networks controlling motor behaviours. http://medicalxpress.com/news/2012-11-biologists-unique-spinal-nerve-cell.html Neuroscience Thu, 08 Nov 2012 12:00:21 EST news271581059 Colon cancer survivors whose diet is heavy in complex sugars and carbohydrate-rich foods are far more likely to have a recurrence of the disease than are patients who eat a better balance of foods, a new study by Dana-Farber Cancer Institute researchers indicates. http://medicalxpress.com/news/2012-11-starchy-high-carbohydrate-diet-recurrence.html Cancer Wed, 07 Nov 2012 16:00:02 EST news271517732 In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's brain, instruct it to turn in any direction they choose, and even to implant false sensory information, fooling the animal into thinking food was nearby. http://medicalxpress.com/news/2012-09-precisely-targeted-lasers-neurons-worms-brains.html Neuroscience Mon, 24 Sep 2012 10:08:19 EST news267700090 High baseline levels of neuronal activity in the best connected parts of the brain may play an important role in the development of Alzheimer's disease. This is the main conclusion of a new study appearing in PLoS Computational Biology from a group at VU University Medical Center in Amsterdam, the Netherlands. http://medicalxpress.com/news/2012-08-brain-alzheimer-disease.html Alzheimer's disease & dementia Thu, 16 Aug 2012 17:00:06 EST news264345834 Many adults wish to maintain their independence as they age, but health problems often require them to live in assisted-care facilities where they can be observed by medical professionals. Now, technologies developed by University of Missouri researchers could help aging adults stay in their own homes longer while still being monitored by health care providers. http://medicalxpress.com/news/2012-06-sensor-technologies-remotely-aging-adults.html Health Thu, 14 Jun 2012 16:52:17 EST news258911530 A Cleveland Clinic study has detected significant changes in the electroencephalogram (EEG) brain activity patterns of patients receiving chemotherapy. http://medicalxpress.com/news/2012-06-chemobrain-eeg.html Cancer Mon, 04 Jun 2012 10:50:37 EST news258025809 (Medical Xpress) -- Preschool children who are more physically active are more likely to show behavioural problems, a study has found. http://medicalxpress.com/news/2012-05-children.html Psychology & Psychiatry Mon, 07 May 2012 09:30:02 EST news255600727 Exposure to light appears to have therapeutic effects on Alzheimer's disease patients, a Wayne State University researcher has found. http://medicalxpress.com/news/2012-01-treatment-benefits-alzheimer-patients.html Diseases, Conditions, Syndromes Wed, 11 Jan 2012 16:19:51 EST news245521137 How the human brain and human cognitive abilities evolved in less than six million years has long puzzled scientists. A new study conducted by scientists in China and Germany, and published December 6 in the online, open-access journal PLoS Biology, now provides a possible explanation by showing that activity levels of genes in the human brain during development changed substantially compared to chimpanzees and macaques. What's more, these changes might be caused by a handful of key regulatory molecules called microRNAs. http://medicalxpress.com/news/2011-12-path-brain-human-brains-unique.html Genetics Tue, 06 Dec 2011 17:33:26 EST news242415185 A team of neuroscientists at Dartmouth College has shown that different individuals' brains use the same, common neural code to recognize complex visual images. http://medicalxpress.com/news/2011-10-neuroscientists-brain-codes.html Neuroscience Thu, 20 Oct 2011 12:00:01 EST news238330299 After excessively violent events, shoot 'em up games regularly come under scrutiny. In Norway, several first-person shooter games actually disappeared from the market for a while after the killings. Does intense fighting on a flat screen display also result in aggressive behavior in real life? Researchers from the University of Bonn found brain activity patterns in heavy gamers that differed from those of non-gamers. The study's results have just been published in the scientific journal Biological Psychology. http://medicalxpress.com/news/2011-10-violent-games-emotionally-desensitizing.html Psychology & Psychiatry Wed, 12 Oct 2011 12:51:27 EST news237642659
