The cluster-based test model for fMRI data analysis based on Neural Network
Objective Accurately determining the statistical significance of changes in brain images is one of the most critical procedures of functional neuroimaging.Because of their increased sensitivity to spatially extended signals, cluster-size tests(CST) based on Random field theory (RFT) have been widely adopted in fMRI data analysis to detect brain activation.However, most existing CST approaches depend on the duster forming threshold and spatial smoothness level Thus, the performance of CST based on RFT is not stable.That”s because RFT relies on large assumptions and many parameters are estimated empirically ”1”.Neural network can develop an accurate model based on lots of learning information.Thus, we want to design a stable and powerful cluster-size test based on neural network under various smoothness levels and duster-forming threshold in this research.
