Somatotopy-independent reduction of audio-tactile intersensory facilitation for looming sounds within the peripersonal space during arm movements execution.

ABSTRACT: Auditory events occurring in the peripersonal space (PPS) or near specific body parts such as the peritrunk (PTS) and perihand (PHS) space, have been shown to facilitate tactile processing in a somatotopic manner. Furthermore, previous research has demonstrated that audio-tactile intersensory effects are influenced by the execution of full body transport movements (i.e., walking or cycling), so that far-off auditory stimuli that approach the body in a direction coherent with the movement facilitate tactile processing on the body. However, whether these motor-related intersensory effects are modulated by non-transport movements is not known. Here, in two experiments, we sought to determine whether audio-tactile intersensory effects for looming sounds in the PHS and PTS are somatotopically m
