Over the past decade fMRI has been used to great effect to non-invasively
map out human brain function with a relatively high degree of spatial
resolution. Studies using this technique have provided us with many insights
about the neural organization and function of perceptual systems such as
vision, audition, touch, and smell. More recently, researchers have begun to
use fMRI to examine multisensory processing. In this tutorial I will
summarize the emerging fMRI work exploring the neural substrates of
multisensory processing. Examples will be taken from audiovisual speech,
visual-tactile, and auditory-tactile integration studies. I will also
summarize what is currently known about the types of neural signals that
fMRI measures, the limits of this technique in terms of its temporal and
spatial resolution, and the inherent constraints of doing multisensory
research in the environment of an fMRI scanner.
