      abstract     = {On the basis of double dissociations in clinical symptoms
                      of patients with unilateral visuospatial neglect,
                      neuropsychological research distinguishes between different
                      spatial domains (near vs. far) and different spatial
                      reference frames (egocentric vs. allocentric). In this fMRI
                      study, we investigated the neural interaction between
                      spatial domains and spatial reference frames by constructing
                      a virtual three-dimensional world and asking participants to
                      perform either allocentric or egocentric judgments on an
                      object located in either near or far space. Our results
                      suggest that the parietal-occipital junction (POJ) not only
                      shows a preference for near-space processing but is also
                      involved in the neural interaction between spatial domains
                      and spatial reference frames. Two dissociable streams of
                      visual processing exist in the human brain: a ventral
                      perception-related stream and a dorsal action-related
                      stream. Consistent with the perception-action model, both
                      far-space processing and allocentric judgments draw upon the
                      ventral stream whereas both near-space processing and
                      egocentric judgments draw upon the dorsal stream. POJ showed
                      higher neural activity during allocentric judgments
                      (ventral) in near space (dorsal) and egocentric judgments
                      (dorsal) in far space (ventral) as compared with egocentric
                      judgments (dorsal) in near space (dorsal) and allocentric
                      judgments (ventral) in far space (ventral). Because
                      representations in the dorsal and ventral streams need to
                      interact during allocentric judgments (ventral) in near
                      space (dorsal) and egocentric judgments (dorsal) in far
                      space (ventral), our results imply that POJ is involved in
                      the neural interaction between the two streams. Further
                      evidence for the suggested role of POJ as a neural interface
                      between the dorsal and ventral streams is provided by
                      functional connectivity analysis.},
