University of Pittsburgh researchers have reproduced the brain's complex electrical impulses onto models made of living brain cells that provide an unprecedented view of the neuron activity behind memory formation. http://medicalxpress.com/news/2011-05-brain-cell-networks-recreated-view.html Medical research Wed, 25 May 2011 14:14:18 EST news225551633 (Medical Xpress) -- In the last couple of years scientists from the Friedrich Miescher Institute for Biomedical Research have developed new strategies to stimulate individual brain cells with light. Optogenetic technologies were named "Method of the Year" by the leading scientific journal Nature Methods in 2010. FMI scientists not only apply this to meet their biomedical needs but refine the tool as well. A recent publication in PNAS is further testimony to this distinctive expertise at the FMI. http://medicalxpress.com/news/2011-05-forefront-optogenetics.html Medical research Tue, 24 May 2011 12:39:02 EST news225459527 (Medical Xpress) -- New data offer hints to why Parkinson's disease so selectively harms brain cells that produce the chemical dopamine, say researchers at Washington University School of Medicine in St. Louis. http://medicalxpress.com/news/2011-05-disruption-nerve-cell-chain-contribute.html Neuroscience Thu, 12 May 2011 16:35:13 EST news224436895
