Neural correlates of the rubber hand illusion in amputees: A report of two cases

Laura Schmalzl, Andreas Kalckert, Christina Ragnö, H. Henrik Ehrsson
2013 Neurocase  
One of the current challenges in the field of advanced prosthetics is the development of artificial limbs that provide the user with detailed sensory feedback.  ...  Sensory feedback from our limbs is not only important for proprioceptive awareness and motor control, but also essential for providing us with a feeling of ownership or simply put, the sensation that our  ...  These regions represent important nodes in a network encompassing premotor, parietal, insular, and extrastriate visual areas involved in the perception of the own body (Berlucchi & Aglioti, 2010) .  ...

Proprioceptive drift in the rubber hand illusion is intensified following 1 Hz TMS of the left EBA

Andrew Wold, Jakub Limanowski, Henrik Walter, Felix Blankenburg
2014 Frontiers in Human Neuroscience  
Recent research has demonstrated an involvement of the extrastriate body area (EBA), an area of the brain that is typically implicated in the perception of non-face body parts, in illusory body ownership  ...  This difference in "proprioceptive drift" provides the first causal evidence that the EBA is involved in the RHI and subsequently in body representation and further supports the view that the EBA is necessary  ...  Along these lines, a recent fMRI study by Limanowski et al. (2014) demonstrated an involvement of the EBA in illusory body ownership.  ...

That's not quite me: limb ownership encoding in the brain

Jakub Limanowski, Felix Blankenburg
2015 Social Cognitive and Affective Neuroscience  
With congruent stimulation of one's limb together with a fake counterpart, an illusory self-attribution of the fake limb can be induced.  ...  These results offer new insights into the differential representation of the real body vs a body that is temporarily self-attributed following the resolution of multisensory conflict.  ...  Acknowledgements We thank Evgeniya Kirilina and Bernhard Spitzer for helpful comments and technical advice, and Simon Ludwig for assistance during the behavioral experiment.  ...

Distinct illusory own-body perceptions caused by damage to posterior insula and extrastriate cortex

Lukas Heydrich, Olaf Blanke
2013 Brain  
One class of such disorders is autoscopic phenomena, which are defined as illusory own-body perceptions, during which patients experience the visual illusory reduplication of their own body in extrapersonal  ...  The present data suggest that the autoscopic hallucination is a visuo-somatosensory deficit implicating extrastriate cortex and is, despite the visual hallucination of the own body, not associated with  ...  Tadokoro Supplementary material Supplementary material is available at Brain online.  ...

The Senses of Agency and Ownership: A Review

Niclas Braun, Stefan Debener, Nadine Spychala, Edith Bongartz, Peter Sörös, Helge H. O. Müller, Alexandra Philipsen
2018 Frontiers in Psychology  
ACKNOWLEDGMENTS This review article is a reworked excerpt from a published, but non-peer reviewed introduction chapter of a Ph.D. thesis (Braun, 2017) . We acknowledge the support of Dr.  ...  An interesting philosophical implication that Wegner derives from his account is that SoA is illusory, in the sense that our "experience of consciously willing an action" is not causally involved in the  ...  In short, although several brain regions have been proposed to contribute to SoO, a consistent picture with respect to the exact involvements of the mentioned areas is still missing.  ...

Introduction to special issue on body representation: feeling, seeing, moving and observing

Ellen Poliakoff
