(Medical Xpress)—Even with a constant task, human performance fluctuates in time-scales from seconds to minutes in a fractal manner. In a recent study a Finnish research group found that the individual variability in the brain dynamics as indexed by the neuronal scaling laws predicted the individual behavioral variability and the conscious detection of very weak sensory stimuli. These data indicate that individual neuronal dynamics underlie the individual variability in human cognition and performance. Results may also have a strong impact in understanding the neuronal mechanism of neuropsychiatric diseases in which behavioral dynamics are abnormal. http://medicalxpress.com/news/2013-02-memories-brain-streaks-individual-behaviour.html Neuroscience Tue, 12 Feb 2013 16:46:37 EST news279909984 (Medical Xpress)—One of the most popular intervention therapies for children with autism spectrum disorders (ASD) lacks scientific support according to a literature review published by University of Texas at Austin professor Mark O'Reilly and an international team of scientists. http://medicalxpress.com/news/2012-11-popular-autism-treatment-lacks-scientific.html Autism spectrum disorders Tue, 20 Nov 2012 08:17:15 EST news272621823 Researchers have mapped the precise 3-D atomic structure of a thin protein filament critical for cells in the inner ear and calculated the force necessary to pull it apart. http://medicalxpress.com/news/2012-11-bond-proteins-critical.html Medical research Wed, 07 Nov 2012 13:00:01 EST news271507105 A team at Children's National Medical Center has found that external stimulation has an impact on the postnatal development of a specific region of the brain. Published in Nature Neuroscience, the study used sensory deprivation to look at the growth and collection of NG2-expressing oligodendrocyte progenitor cells (NG2 cells) in the sensory cortex of the brain. This type of research is part of the Center for Neuroscience Research focus on understanding the development and treatment of white matter diseases. http://medicalxpress.com/news/2012-08-external-impacts-white-postnatal-brain.html Medical research Mon, 13 Aug 2012 15:19:21 EST news264089950 (HealthDay) -- Sensory therapies using brushes, swings and other play equipment are increasingly used by occupational therapists to treat children with developmental issues such as autism, but a large pediatricians organization says there isn't much evidence that such therapies actually work. http://medicalxpress.com/news/2012-05-sensory-therapies-autism.html Autism spectrum disorders Mon, 28 May 2012 10:20:01 EST news257416894 The next time you set a trap for that rat running around in your basement, here's something to consider: you are going up against an opponent whose ability to assess the situation and make decisions is statistically just as good as yours. http://medicalxpress.com/news/2012-03-rats-humans-decision-making-involves-combining.html Neuroscience Tue, 13 Mar 2012 17:00:06 EST news250869372 Famed violinist Itzhak Perlman sees a deep forest green whenever he plays a B-flat on his Stradivarius' G string.
