(Medical Xpress)—Researchers have found that missteps in a basic cellular process, RNA splicing, is the culprit behind a class of rare neurological disorders manifested by intellectual disability and stunted development. http://medicalxpress.com/news/2013-03-errors-rna-splicing-class-neurological.html Genetics Fri, 29 Mar 2013 06:50:17 EST news283758597 It's the least understood organ in the human body: the brain, a massive network of electrically excitable neurons, all communicating with one another via receptors on their tree-like dendrites. Somehow these cells work together to enable great feats of human learning and memory. But how? http://medicalxpress.com/news/2012-12-years-electrical-role-dendritic-spines.html Neuroscience Wed, 05 Dec 2012 13:49:29 EST news273937762 (Medical Xpress)—Researchers from Australia and the USA have made a unique discovery about how the brain computes sensory information. http://medicalxpress.com/news/2012-11-neuron-huge-impact-brain-behaviour.html Neuroscience Thu, 15 Nov 2012 07:20:01 EST news272184758 UC Irvine oncologists are looking for new ways to treat glioblastoma multiforme, the deadliest type of brain cancer. While surgery followed by chemotherapy and radiation is the current standard of care, it doesn't fully eliminate the cancer. The goal is to develop an additional therapy that seeks out and destroys the cancer cells that inevitably remain. http://medicalxpress.com/news/2012-11-brain-cancer-breakthrough-experimental-vaccine.html Cancer Wed, 14 Nov 2012 08:22:21 EST news272103731 Every activity in the brain involves the transfer of signals between neurons. Frequently, as many as one thousand signals rain down on a single neuron simultaneously. To ensure that precise signals are delivered, the brain possesses a sophisticated inhibitory system. Stefan Remy and colleagues at the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn have illuminated how this system works. http://medicalxpress.com/news/2012-09-brain-filter-transmission.html Neuroscience Thu, 06 Sep 2012 11:23:50 EST news266149420 Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell. http://medicalxpress.com/news/2012-08-video-traffic-brain-cell.html Neuroscience Wed, 22 Aug 2012 16:02:04 EST news264870082 Korean scientists have used tiny stars, squares and triangles as a toolkit to create live neural circuits in a dish. http://medicalxpress.com/news/2012-07-triangles-neural-circuits-dish.html Neuroscience Thu, 19 Jul 2012 19:00:02 EST news261932412 (Medical Xpress) -- How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the junctions connecting nerve cells. Synapses also require new proteins in order to show changes in their strength (synaptic plasticity). Historically, scientists have focused on the cell body as the place where the required proteins are synthesized. However, in recent years there has been increasing focus on the dendrites and axons (the compartments that meet to form synapses) as a potential site for protein synthesis. http://medicalxpress.com/news/2012-05-global-local-roles-protein-synthesis.html Neuroscience Thu, 10 May 2012 06:53:34 EST news255851578 Armed with a new ability to find retinal anomalies at the cellular level, neurobiologists at St. Jude Children's Research Hospital have made a discovery they hope will ultimately lead to a treatment for cancer of the retina. http://medicalxpress.com/news/2011-12-ornl-image-analysis-prowess-advances.html Medical research Wed, 21 Dec 2011 16:47:21 EST news243708428 Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development. http://medicalxpress.com/news/2011-12-scientists-advances-neuroscience-vision.html Neuroscience Tue, 06 Dec 2011 09:29:02 EST news242386131
