    Institute of Biomedicine, Department of Physiology, University of Helsinki, Finland
    Cereb Cortex 8:743-52. 1998
    ..The results suggest that the performance of a visuospatial working memory task engages a network of distributed brain areas and that areas in the dorsal visual pathway are engaged in mnemonic processing of visuospatial information...
