1. The medial superior temporal area (MST) is an extrastriate area of the macaque visual cortex. Cells in MST have large receptive fields and respond to moving stimuli with directional selectivity. We previously suggested that the dorsal part of MST is mainly involved in analysis of field motion caused by movements of the animal itself, because most cells(More)
Cross-modal binding in auditory-visual speech perception was investigated by using the McGurk effect, a phenomenon in which hearing is altered by incongruent visual mouth movements. We used functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). In each experiment, the subjects were asked to identify spoken syllables ('ba',(More)
Infant monkeys were reared with no exposure to any faces for 6-24 months. Before being allowed to see a face, the monkeys showed a preference for human and monkey faces in photographs, and they discriminated human faces as well as monkey faces. After the deprivation period, the monkeys were exposed first to either human or monkey faces for a month. Soon(More)
I n perceiving the sound produced by the movement of a visible object, the brain coordinates the auditory and visual input 1–3 so that no delay is noticed even though the sound arrives later (for distant source objects, such as aircraft or firework displays, this is less effective). Here we show that coordination occurs because the brain uses information(More)
BACKGROUND Audition provides important cues with regard to stimulus motion although vision may provide the most salient information. It has been reported that a sound of fixed intensity tends to be judged as decreasing in intensity after adaptation to looming visual stimuli or as increasing in intensity after adaptation to receding visual stimuli.
