      abstract     = {Attentional orientation to a spatial cue and
                      reorientation-after invalid cueing-are mediated by two
                      distinct networks in the human brain. A bilateral dorsal
                      frontoparietal network, comprising the intraparietal sulcus
                      (IPS) and the frontal eye fields (FEF), controls the
                      voluntary deployment of attention and may modulate visual
                      cortex in preparation for upcoming stimulation. In contrast,
                      reorienting attention to invalidly cued targets engages a
                      right-lateralized ventral frontoparietal network comprising
                      the temporoparietal junction (TPJ) and ventral frontal
                      cortex. The present fMRI study investigated the functional
                      architecture of these two attentional systems by
                      characterizing effective connectivity during lateralized
                      orienting and reorienting of attention, respectively.
                      Subjects performed a modified version of Posner's
                      location-cueing paradigm. Dynamic causal modeling (DCM) of
                      regional responses in the dorsal and ventral network,
                      identified in a conventional (SPM) whole-brain analysis, was
                      used to compare different functional architectures. Bayesian
                      model selection showed that top-down connections from left
                      and right IPS to left and right visual cortex, respectively,
                      were modulated by the direction of attention. Moreover,
                      model evidence was highest for a model with directed
                      influences from bilateral IPS to FEF, and reciprocal
                      coupling between right and left FEF. Invalid cueing enhanced
                      forward connections from visual areas to right TPJ, and
                      directed influences from right TPJ to right IPS and IFG
                      (inferior frontal gyrus). These findings shed further light
                      on the functional organization of the dorsal and ventral
                      attentional network and support a context-sensitive
                      lateralization in the top-down (backward) mediation of
                      attentional orienting and the bottom-up (forward) effects of
                      invalid cueing.},
