We used event related design to analyze the imaging data. SPM5 uses general linear model (GLM) to assess task-related changes in blood oxygen level dependence (BOLD) signal. Six head-movement parameters derived from the realignment were included as covariates. The design matrix modeled WIN, ...
Therefore, fMRI can dynamically analyze the activation changes in the spatial structure of brain regions, which cannot be done by other methods. Compared with static MRI, fMRI presents dynamic profile on this basis. Critical degrees was set as the only variable, so as to improve the rationality...
