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.},
