METHOD FOR DETERMINING AN INTRACORTICAL WORKING STATE OF A FUNCTIONAL NETWORK IN THE BRAIN

摘要

A method for determining an intracortical working state of a functional network of the brain includes acquiring a number of first blood oxygen saturation level time point vectors of a number of gray matter voxels of a cortex of a brain functional network template, each of the blood oxygen saturation level time point vectors respectively having blood oxygen saturation level signals of each of the gray matter voxels at a number of continuous time points in a particular time period. The method further includes clustering the blood oxygen saturation level time point vectors as a number of gray matter voxel cooperative time point categories by taking the blood oxygen saturation level signals as objects, the gray matter voxel cooperative time point categories being sets of a number of discrete time points of the gray matter voxels respectively in the particular time period. The method includes determining the number of gray matter voxel cooperative time point categories as the intracortical working state of the first cortex.
