Recent advances in measurement technology enables us to obtain spatotemporal data from neural systems as imaging data. In this study, we propose a statistical method to estimate nonlinear spatiotemporal membrane dynamics of active dendrites. We formulate generalized state space model of active dendrite, based on multi-compartment model. Membrane dynamics and its underlying electrical properties are simultaneously estimated by using sequential Monte-Carlo method and EM algorithm. Using the proposed method, we show that nonlinear spatiotemporal dynamics in active dendritic can be extracted from partially observable data.
