Networks for multi-sensory attention and working memory
Converging evidence from fMRI and EEG shows that audtiory spatial attention engages the same fronto-parietal network associated with visuo-spatial attention. This network is distinct from an auditory-biased processing network that includes other frontal regions; this second network is can be recruited when observers extract rhythmic information from visual inputs. We recently used a dual-task paradigm to examine whether this "division of labor" between a visuo-spatial network and an auditory-rhythmic network can be observed in a working memory paradigm. We varied the sensory modality (visual vs. auditory) and information domain (spatial or rhythmic) that observers had to store in working memory, while also performing an intervening task. Behavior, pupilometry, and EEG results show a complex interaction across the working memory and intervening tasks, consistent with two cognitive control networks managing auditory and visual inputs based on the kind of information being processed.
