Canonical PTA3 modes on fMRI data

  • Now an example with fMRI data (brain x time x subjects) for a multi-subject verbal experiment.(To perform a multi-subject analysis coregistration of the 3D volumes are performed using motion correction and registration to a standard.) The first analysis is without metrics or penalisations (canonical). The time series (for each voxel and eac subject) were detrended, and each subject was scaled to variance one. (here the brain is only one slice: the label on the brain component is wrong slices all the 14:18 were not used.)

    Each set of triple of components are viewed together and interpreted simultaneously.
