Abstract
Neurophysiological studies demonstrate that somatosensory neurons in parietal lobe of monkeys can respond to visual stimulus presented in peripersonal space. Interestingly, some of these neurons are reported to respond to visual stimulus presented in the peripersonal space not only near the monkeys' body part but also in the corresponding space of their partner who faced them. A recent fMRI study showed the shared representations of peripersonal space in humans as well. The aim of the present study was to provide the behavioral evidence for such representations in humans by using psychophysical measurements.
