Embodiment Construction
[0028] Under the stimulation of the Chinese Facial Expression Video System (CFEVS), the subjects scanned to obtain task state data, and then scanned to obtain rest state data. The fMRI analysis software SPM was used to preprocess the data spatially and temporally, including head movement correction, spatial normalization, Gaussian smoothing filtering, time normalization and high-pass filtering to remove low-frequency noise, and after operation, the data set was obtained. Use PCA (Tipping M, BishopC.Mixtures of probabilistic principal component analyzers.NeuralComputation, 1999, 11: 443-482) to reduce the dimension of task state data and rest state data, and retain the main information; then use the time domain Independent component analysis (ICA) extracts 25 independent components of each of the two types of data; and then finds out the range of functional signal components by performing correlation traversal between the independent components of the two types of data, and obta...
