| Abstract(in English) | There is a trade-off between amount of energy consumption and time resolution for synaptic inputs in a single neuron; the time resolution should be high in case of low membrane resistance, whereas the amount of energy consumption should be low in case of high membrane resistance. Therefore, a single neuron should have a non-uniform distribution of membrane resistance to maintain high time resolution while saving the amount of energy consumption. In this paper, we estimated the distribution of membrane resistance in a single neuron based on the results by optical method for a hippocampal CA1 slice and discuss the functionality of the non-uniform membrane resistance. In the estimated distribution, the membrane resistance decreased drastically at distal apical dendrite. This implies that a single neuron achieves energy-saving while maintaining high time resolution. |
