title = "Spatially local and temporally smooth PCA for fMRI",
abstract = "PCA has found use as an exploratory technique for fMRI analysis. However underlying it is an implicit model that while allowing temporal non-stationary covariance assumes the same covariance structure for all voxels. Here we relax this assumption for the first time by developing a version of PCA that allows the covariance structure to vary spatially. The new method is applied to real data and provides interesting new insight.",
