Research Abstract

We conducted the measurement of jitter perception associated with frequency change of alpha wave to prove the hypothesis of alpha wave clock. Then we performed the analysis of coupling between MEG data and jitter frequency. We have acquired promising result for applying the result to decoding the perception of numerical characters. We also succeeded in identification of the contribution of Corollary Discharge for the origin of alpha wave. At the same time, we constructed a method based on the Bayes theory to estimate signal parameters embedded in the noisy data in a real time manner using GPU.
