Abstract (in Japanese) (See Japanese page) 
(in English) Neurons can be interpreted as an encoder transforming some specific external stimuli into spikes, and the mechanism of this neural encoder obey the neural dynamics. To relate the encoding process to the properties of ion channels, some researchers have investigated the relation between the structures of the stimuli associated with neural spikes (STE: Spike Triggered stimulus Ensemble) and the neural dynamics. In this report, we formulate the nth moment of STE (MSTEn) of the neurons spiking periodically with the phase response curves (PRCs), and propose a new calculation technique to derive MSTEn based on the higher-order perturbation expansion. The following three results were obtained for neural oscillators. 1. The approximated expression relating STC to PRC was derived. 2. The relation between STA and STC were disclosed analytically. 3. It became clear what factor mainly breaks the approximate expression holding between STA and PRC, which had derived in the previous work.
