abstract = {Momentary lapses in attention disrupt goal-directed
behaviors, and have been associated with increased
pre-stimulus activity in the default mode network (DMN). The
human brain often encounters multisensory inputs. It remains
unknown, however, whether the neural mechanisms underlying
attentional lapses are supra-modal or modality-dependent. To
answer this question in the present functional magnetic
resonance imaging (fMRI) study, we asked participants to
respond to either visual or auditory targets in a
multisensory paradigm, and focused on the pre-stimulus
neural signals underlying attentional lapses, which resulted
in impaired task performance, in terms of both delayed RTs
and behavioral errors, in different sensory modalities.
Behaviorally, mean reaction times (RTs) were equivalent
between the visual and auditory modality. At the neural
level, increased pre-stimulus neural activity in the
majority of the core DMN regions, including medial
prefrontal cortex (mPFC), posterior cingulate cortex (PCC),
and left angular gyrus (AG), predicted delayed RTs more
effectively in the visual than auditory modality.
Especially, increased pre-stimulus activity in the mPFC
predicted not only delayed RTs but also errors, more
effectively in the visual than auditory modality. On the
other hand, increased pre-stimulus activity in the anterior
precuneus predicted both prolonged RTs and errors more
effectively in the auditory than visual modality. Moreover,
a supra-modal mechanism was revealed in the left middle
temporal gyrus (MTG), which belongs to the posterior DMN.
Increased pre-stimulus neural activity in the left MTG
predicted impaired task performance in both the visual and
auditory modality. Taken together, the core DMN regions
manifest vision-dependent mechanisms of attentional lapses
while a novel region in the anterior precuneus shows
audition-dependent mechanisms of attentional lapses.
Moreover, left MTG in the posterior DMN manifests a
supra-modal mechanism of attentional lapses, independent of
the modality of sensory inputs.},
