Abstract:
|
In functional magnetic resonance imaging (fMRI), it is known that there exists spatio-temporal correlation between voxels over time. Attempts have been made to model voxel spatio-temporal correlations in fMRI data. In fMRI, preprocessing of images and voxel time series are almost always performed to "improve" the data. It has been shown that these preprocessing steps can modify the mean image and induce spatio-temporal correlation between voxels that would be uncorrelated without preprocessing. Methods are described to utilize the known correlation from preprocessing that is induced for statistical analysis.
