Being in the dark about your hand: Resolution of visuo-proprioceptive conflict by disowning visible limbs
Description
Conflict between sensory modalities can be resolved by one modality overwriting another. For example, movement of a limb that is visible in a stationary visual afterimage results in selective fading of that limb in the afterimage. We investigated the interaction of these two sensory modalities by inducing a mismatch between visual and proprioceptive hand location. Whereas this discrepancy did not affect the initial appearance of the hand in the afterimage, it did prevent subsequent motion with the hand from affecting the hand's appearance. Location mismatch disconnected the visual and proprioceptive experiences of the hand, "protecting" the visual afterimage from interaction with proprioception. Investigation of subjective higher order bodily experiences showed a strong negative correlation between afterimage disruption and the subjective feeling of ownership, suggesting that the brain can resolve multimodal location mismatch by 'disowning' a visible limb, and that the interaction between proprioception and vision is mediated by higher order bodily experiences.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
