      abstract     = {Neuroimaging studies have repeatedly reported findings of
                      activation in frontoparietal regions that largely overlap
                      across various cognitive functions. Part of this
                      frontoparietal activation has been interpreted as reflecting
                      attentional mechanisms that can adaptively be directed
                      towards external stimulation as well as internal
                      representations (internal attention), thereby generating the
                      experience of distinct cognitive functions. Nevertheless,
                      findings of material- and task-specific activation in
                      frontal and parietal regions challenge this internal
                      attention hypothesis and have been used to support more
                      modular hypotheses of cognitive function. The aim of this
                      review is twofold: First, it discusses evidence in support
                      of the concept of internal attention and the so-called
                      dorsal attention network (DAN) as its neural source with
                      respect to three cognitive functions (working memory,
                      episodic retrieval, and mental imagery). While DAN
                      activation in all three functions has been separately linked
                      to internal attention, a comprehensive and integrative
                      review has so far been lacking. Second, the review examines
                      findings of material- and process-specific activation within
                      frontoparietal regions, arguing that these results are well
                      compatible with the internal attention account of
                      frontoparietal activation. A new model of cognition is
                      presented, proposing that supposedly different cognitive
                      concepts actually rely on similar attentional network
                      dynamics to maintain, reactivate and newly create internal
                      representations of stimuli in various modalities.
                      Attentional as well as representational mechanisms are
                      assigned to frontal and parietal regions, positing that some
                      regions are implicated in the allocation of attentional
                      resources to perceptual or internal representations, but
                      others are involved in the representational processes
                      themselves.},
