FIGURE 26.4

Hypothetical neural mechanisms for involuntary cross-modal spatial cueing effects. (a) Integration-based account. Nearly simultaneous auditory and visual stimuli first activate unimodal auditory and visual cortical regions and then converge upon a multisensory region (AV). Audiovisual interaction within multisensory region feeds back to boost activity in visual cortex. (b) Attention-based account. An auditory cue elicits a shift of spatial attention in a multisensory representation, which leads to pre-target biasing of activity in visual cortex and ultimately boosts target-related activity in visual cortex.
