Modern brain imaging techniques have now made it possible to study the neural sites and
mechanisms underlying crossmodal processing in the human brain. This paper reviews …

Understanding the conditions under which the brain integrates the different sensory streams
and the mechanisms supporting this phenomenon is now a question at the forefront of …

Recent anatomical, physiological, and neuroimaging findings indicate multisensory
convergence at early, putatively unisensory stages of cortical processing. The objective of …

Viewing a speaker's articulatory movements substantially improves a listener's ability to
understand spoken words, especially under noisy environmental conditions. It has been …

This functional magnetic resonance imaging study investigated the impact of early auditory
deprivation and/or use of a visuospatial language [American sign language (ASL)] on the …

Neurophysiological research suggests that understanding the actions of others harnesses
neural circuits that would be used to produce those actions directly. We used fMRI to …

The perception of objects is a cognitive function of prime importance. In everyday life, object
perception benefits from the coordinated interplay of vision, audition, and touch. The …

Speech is perceived both by ear and by eye. Unlike heard speech, some seen speech
gestures can be captured in stilled image sequences. Previous studies have shown that in …

Human speech perception is profoundly influenced by vision. Watching a speaker's mouth
movements significantly improves comprehension, both for normal listeners in noisy …

Recent studies have yielded contradictory evidence on whether visual speech perception
(watching articulatory gestures) can activate the human primary auditory cortex. To …
