The present study explores a novel spatiotemporal technique using the fixed effect model for the analysis of functional brain images and propose a novel approach to obtain the least square estimation of the signal subspace of activated voxels. The spatial and temporal domain correlations are incorporated using appropriate prior models and the possibility of using the Markov property to incorporate the spatial domain correlations are investigated.
