Abstract: Incoming signals from different sensory modalities are initially processed in anatomically separate regions in human brain, and then be integrated in multimodal association cortices. From human imaging studies about audiovisual integration in speech perception it is clear that auditory and visual inputs can influence each other and be integrated primarily in the left posterior superior temporal sulcus (STS). Increasingly, this integrative effect should be constrainted by space and time. Further trends will benefit from establishing the most suitable experimental paradigms and analytic methods for multisensory integration involved in more complex domain.

Key words: audiovisual integration, superior temporal sulcus, time, space
