Evoked potentials and intersensory information processing

Traditionally, researchers have studied each sensory modality and its effect on human perception as a discrete process. However, every-day perceptual experiences integrate a variety of sensory inputs. Examining each sensory path independently can lead to a partial understanding of their total capabilities and their impact on the cognitive function. Normally, two or more modalities can carry information about the same event or different sensory modalities can be simultaneously stimulated by different events. The effects on interstimulus interval on the bisensory evoked potential are reported for cases when the auditory and visual stimulus are separated by as much as 100 ms.
