      abstract     = {The ability to select, within the complexity of sensory
                      input, the information most relevant for our purposes is
                      influenced by both internal settings (i.e., top-down
                      control) and salient features of external stimuli (i.e.,
                      bottom-up control). We here investigated using fMRI the
                      neural underpinning of the interaction of top-down and
                      bottom-up processes, as well as their effects on
                      extrastriate areas processing visual stimuli in a
                      category-selective fashion. We presented photos of bodies or
                      buildings embedded into frequency-matched visual noise to
                      the subjects. Stimulus saliency changed gradually due to an
                      altered degree to which photos stood-out in relation to the
                      surrounding noise (hence generating stronger bottom-up
                      control signals). Top-down settings were manipulated via
                      instruction: participants were asked to attend one stimulus
                      category (i.e., “is there a body?” or “is there a
                      building?”). Highly salient stimuli that were inconsistent
                      with participants’ attentional top-down template activated
                      the inferior frontal junction and dorsal parietal regions
                      bilaterally. Stimuli consistent with participants’ current
                      attentional set additionally activated insular cortex and
                      the parietal operculum. Furthermore, the extrastriate body
                      area (EBA) exhibited increased neural activity when
                      attention was directed to bodies. However, the latter effect
                      was found only when stimuli were presented at intermediate
                      saliency levels, thus suggesting a top-down modulation of
                      this region only in the presence of weak bottom-up signals.
                      Taken together, our results highlight the role of the
                      inferior frontal junction and posterior parietal regions in
                      integrating bottom-up and top-down attentional control
                      signals.},
