Generalized Cable Theory and Impedance of the Neural Tissue
Cable theory is fundamental to understanding neurons' electric behavior and their extended dendritic structure. This theory was introduced by Wilfrid Rall more than half a century ago and is widely used today for modeling the voltage and current flow in neuronal and dendritic structures. The classic cable theory was derived assuming that the extracellular medium is either inexistent or modeled as a resistor. For modeling neurons in more realistic situations, where the extracellular medium has more complex electric properties, it is necessary to generalize Rall's cable equations. We present such generalized cable equations and show that the nature of the surrounding extracellular medium can exert non-negligible influences on the cable properties of neurons.
Short Bio (of Speaker):
Claude Bedard is a physicist affiliated with the CNRS and the College de France. He holds a Ph.D. in Theoretical Physics from the Université Laval (Québec, PQ, Canada) and pursued his postdoctoral training at the group of computational and experimental neuroscience of renowned neuroscientist Alain Destexhe, at CNRS, Gif-sur-Yvette, in France. Claude is an expert in classical electrodynamics and has made pioneering contributions in extending Maxwell's equations and cable theory to studying electromagnetic phenomena in brain tissue.
