Abstract(in English) | We would bridge a gap between cell and network dynamics by collaboration of theorists and physiologists through the commonage of the NEURON simulator. The effect of a dendritic backpropagation on neural interaction has not yet elucidated adequately. A membrane can be modeled by a parallel circuit composed of nonlinear voltage-dependent inward currents and outward currents. In this case, if the inward current and outward current are balanced, the effective membrane impedance diverges to ±∞. This singularity is universal in nerve membranes. By using the NEURON simulator, it was demonstrated that an EPSP collided with a backpropagating action potential was dramatically changed by the regulation of the outward current, reflecting the balancing singularity. Next, we measured phase response curves of a single neuron, and then, we estimated the dynamics of neural networks. It was demonstrated that a network dynamics was dramatically changed by the regulation of the outward current in the mode of the backpropagation generation, reflecting the balancing singularity. |
