FIGURE 7.3

Scenarios for large-scale neural communication during cross-modal perception. The model proposed here is compatible with a number of different patterns of neural interactions. The figure refers to the case of audiovisual interactions. (a) Multisensory interactions by coherence change between early sensory areas. (b) Alternatively, changes in neural coherence or power might occur mainly within or between multisensory association cortices, e.g., superior temporal and parietal regions. (c) Combining both scenarios, neural synchrony among unimodal regions could also be associated with enhanced oscillatory activity in multisensory areas. (d) Multisensory perception might also involve oscillatory activity in frontal regions, which is likely to exert a modulatory influence on temporal patterns in parietal and temporal regions.
