Abstract (in Japanese) (See Japanese page) 
(in English) Statistical methods for estimating dendritic membrane properties,
including membrane resistance as a representative example, from observed noisy signals have been proposed in the last decade. Most of these methods assume membrane properties to be uniform over a dendritic tree. However, it is known that these properties are actually non-uniformly distributed,
and even change steeply along a dendrite. In this study, we propose a statistical method for estimating membrane resistance distributions from observed membrane potentials, applicable to any distribution form. Dynamics of membrane potential is expressed in the cable equation, and membrane resistance distributions are expressed in the line process model.
The line process model assumes a piecewise smooth distribution. Hence, even in the case where there are steep changes, our method can accurately estimate the membrane resistance distribution.
