  • Title: Subspace approaches for FMRI time series estimation.
    Author: Niskanen EI, Tarvainen MP, Kononen M, Soininen H, Karjalainen PA.
    Journal: Annu Int Conf IEEE Eng Med Biol Soc; 2007; 2007():5485-8. PubMed ID: 18003253.
    Abstract:
    In this paper, we present a subspace approach for functional magnetic resonance imaging (fMRI) time series analysis. The signal subspace is formed of the eigenvectors of data correlation matrix. The approach is utilized both for single-trial estimation of blood oxygenation level dependent (BOLD) responses in fMRI time series and for studying the functional connectivity of BOLD responses from different spatial areas.
