Investigating peri-limb interaction between nociception and vision using spatial depth

Results showed that, as compared to the control condition, participants' judgements were biased in favor of the visual stimuli the closest to the stimulated hand, irrespective of their distance from the trunk. This finding supports the idea that the mechanisms underlying nociceptive-visual interactions are based on spatial representations that primarily use the stimulated limb rather than the whole body as a coordinate system.
