Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are repaired at their farthest reaches after injury. The research was recently published in the Journal of Neuroscience. http://medicalxpress.com/news/2013-03-axons-nerve-regeneration-injury.html Neuroscience Fri, 22 Mar 2013 13:10:01 EST news283175564 (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
