      abstract     = {Sustained responsiveness to external stimulation is
                      fundamental to many time-critical interactions with the
                      outside world. We used functional magnetic resonance imaging
                      during speeded stimulus detection to identify convergent and
                      divergent neural correlates of maintaining the readiness to
                      respond to auditory, tactile, and visual stimuli. In
                      addition, using a multimodal condition, we investigated the
                      effect of making stimulus modality unpredictable. Relative
                      to sensorimotor control tasks, all three unimodal detection
                      tasks elicited stronger activity in the right
                      temporo-parietal junction, inferior frontal cortex, anterior
                      insula, dorsal premotor cortex, and anterior cingulate
                      cortex as well as bilateral mid-cingulum, midbrain,
                      brainstem, and medial cerebellum. The multimodal detection
                      condition additionally activated left dorsal premotor cortex
                      and bilateral precuneus. Modality-specific modulations were
                      confined to respective sensory areas: we found activity
                      increases in relevant, and decreases in irrelevant sensory
                      cortices. Our findings corroborate the modality independence
                      of a predominantly right-lateralized core network for
                      maintaining an alert (i.e., highly responsive) state and
                      extend previous results to the somatosensory modality.
                      Monitoring multiple sensory channels appears to induce
                      additional processing, possibly related to stimulus-driven
                      shifts of intermodal attention. The results further suggest
                      that directing attention to a given sensory modality
                      selectively enhances and suppresses sensory processing-even
                      in simple detection tasks, which do not require inter- or
                      intra-modal selection.},
