      abstract     = {Hemispatial neglect, after unilateral lesions to parietal
                      brain areas, is characterized by an inability to respond to
                      unexpected stimuli in contralesional space. As the visual
                      field's horizontal meridian is most severely affected, the
                      brain networks controlling visuospatial processes might be
                      tuned explicitly to this axis. We investigated such a
                      potential directional tuning in the dorsal and ventral
                      frontoparietal attention networks, with a particular focus
                      on attentional reorientation. We used an
                      orientation‐discrimination task where a spatial precue
                      indicated the target position with $80\%$ validity. Healthy
                      participants (n = 29) performed this task in two runs and
                      were required to (re‐)orient attention either only along
                      the horizontal or the vertical meridian, while fMRI and
                      behavioral measures were recorded. By using a general linear
                      model for behavioral and fMRI data, dynamic causal modeling
                      for effective connectivity, and other predictive approaches,
                      we found strong statistical evidence for a reorientation
                      effect for horizontal and vertical runs. However, neither
                      neural nor behavioral measures differed between vertical and
                      horizontal reorienting. Moreover, models from one run
                      successfully predicted the cueing condition in the
                      respective other run. Our results suggest that activations
                      in the dorsal and ventral attention networks represent
                      higher‐order cognitive processes related to spatial
                      attentional (re‐)orientating that are independent of
                      directional tuning and that unilateral attention deficits
                      after brain damage are based on disrupted interactions
                      between higher‐level attention networks and sensory
                      areas.},
