Here we show in contradiction to the common view, that this process is merely governed by electric transport than diffusion forces. http://precedings.nature.com/documents/2304/version/2 Mon, 22 Jun 2009 10:19:39 UTC The Predominance of Electric Transport in Synaptic Transmission hdl:10101/npre.2009.2304.2 2009-06-22 Hamid Reza Noori Nature Precedings 2009-06-22T10:19:39Z Manuscript Neuroscience http://creativecommons.org/licenses/by/3.0/ http://precedings.nature.com/documents/3348/version/1 The problem of the transformation of microscopic information to the macroscopic level is an intriguing challenge in computational neuroscience, but also of general mathematical importance. Here, a phenomenological mathematical model is introduced that simulates the internal information processing of brain compartments. Synaptic potentials are integrated over small number of realistically coupled neurons to obtain macroscopic quantities. The striatal complex, an important part of the basal ganglia circuit in the brain for regulating motor activity, has been investigated as an example for the validation of the model. http://precedings.nature.com/documents/3348/version/1 Fri, 19 Jun 2009 14:06:35 UTC Averaging Transformations of Synaptic Potentials on Networks hdl:10101/npre.2009.3348.1 2009-06-19 Hamid Reza Noori Nature Precedings 2009-06-19T14:06:35Z Manuscript Neuroscience http://creativecommons.org/licenses/by/3.0/
