}Intracranial recordings from three human subjects provide the first direct electrophysiological evidence for audio-visual multisensory processing in the human superior parietal lobule (SPL). Auditory and visual sensory inputs project to the same highly localized region of the parietal cortex with auditory inputs arriving considerably earlier (30 ms) than visual inputs (75 ms). Multisensory integration processes in this region were assessed by comparing the response to simultaneous audio-visual…Â

The bouncing percept occurs when early attentional deployment facilitates multisensory integration modulating visual perception and early activation of the unimodal areas and later involvement of the attention-related areas are associated with the passing percept.
Neural Responses in Parietal and Occipital Areas in Response to Visual Events Are Modulated by Prior Multisensory Stimuli
- Psychology, BiologyPloS one
- 2013
The experiments suggest that processing of a visual stimulus can be affected by the presence of an immediately prior multisensory event, and relatively long-lasting interactions generated by the initial auditory and visual stimuli altered theprocessing of a subsequent visual stimulus.

The impact of brain damage on MSI in stroke patients using a well-established psychophysical paradigm is demonstrated using the redundant target paradigm, the first to demonstrate the impact of head injury on multisensory integration in individuals with brain damage.
TMS of posterior parietal cortex disrupts visual tactile multisensory integration
- Psychology, BiologyThe European journal of neuroscience
- 2010
A model in which the posterior parietal cortex contains a map of space around the hand that receives input from both the visual and somatosensory modalities is supported, in which activity in this map is likely to be the neural substrate for visual–tactile multisensory integration.

The efficacy of using an analytic approach informed by electrophysiology to identify multisensory integration sites in humans is demonstrated and the particular network of brain areas implicated in these crossmodal integrative processes are suggested to be dependent on the nature of the correspondence between the different sensory inputs.

This study investigated whether LIP neurons process stimuli of other modalities besides the visual one by comparing their activity in auditory and visual saccade tasks, and found that the memory activity of many LIP cells encodes the next planned saccades.

It is found that orienting spatial attention to an irrelevant sound modulates the ERP to a subsequent visual target over modality-specific, extrastriate visual cortex, but only after the initial stages of sensory processing are completed.
