., a feeling of having one's own body) of the phantom limb. Nine upper-limb amputees, five of whom reported recent phantom limb pain, underwent a single 15-min trial of mirror therapy.  ...  Most amputees experience phantom limb, whereby they feel that the amputated limb is still present. In some cases, these experiences include pain that can be alleviated by "mirror therapy."  ...  ACKNOWLEDGMENT We would like to thank Takashi Nomura and Toshihiko Hayashi for their assistance with participant recruitment.  ...

5. Neural Mechanisms of Bodily Self-Consciousness and the Experience of Presence in Virtual Reality [chapter]

Bruno Herbelin, Roy Salomon, Andrea Serino, Olaf Blanke
2015 Human Computer Confluence  
Recent neuroscience research emphasizes the embodied origins of the experience of the self.  ...  This chapter shows that further advances in the understanding of the phenomenon of VR-induced presence might be achieved in connection with advances in the understanding of the brain mechanisms of bodily  ...  We experience the world from the physical location and with an egocentric perspective of the body, which we feel as our own.  ...

Agency over a phantom limb and electromyographic activity on the stump depend on visuomotor synchrony: a case study

Shu Imaizumi, Tomohisa Asai, Noriaki Kanayama, Mitsuru Kawamura, Shinichi Koyama
2014 Frontiers in Human Neuroscience  
ACKNOWLEDGMENTS We would like to thank all the participants for their cooperation, Yoshihiro Shimomura for his technical help during EMG recording, and two anonymous reviewers for their helpful comments  ...  Although recent studies have described many aspects to a sense of agency (e.g., Synofzik et al., 2008) , the key concept is a sense of controlling one's own actions and, therefore, the external proxy  ...  When an individual's action can be seen as his/her own action, he/she can misattribute the viewed action, which can affect actual movement (Nielsen, 1963; Fourneret and Jeannerod, 1998) .  ...

Decreased Corticospinal Excitability after the Illusion of Missing Part of the Arm

Konstantina Kilteni, Jennifer Grau-Sánchez, Misericordia Veciana De Las Heras, Antoni Rodríguez-Fornells, Mel Slater
2016 Frontiers in Human Neuroscience  
Previous studies on body ownership illusions have shown that under certain multimodal conditions, healthy people can experience artificial body-parts as if they were part of their own body, with direct  ...  In this study we wanted to assess (a) whether healthy people can experience 'missing' a body-part through illusory ownership of an amputated virtual body, and (b) whether this would cause corticospinal  ...  Moreover, this modulation in corticospinal excitability of the right hemisphere was found not to be limited to vision of one's own face, but to extend to vision of one's own hand and one's own objects  ...

Understanding Activation Patterns in Shared Circuits: Toward a Value Driven Model

Lisa Aziz-Zadeh, Emily Kilroy, Giorgio Corcelli
2018 Frontiers in Human Neuroscience  
Over the past decade many studies indicate that we utilize our own motor system to understand the actions of other people.  ...  Here we propose adapting a "value-driven" model to explain discrepancies in the human mirror system literature and to incorporate this model with existing models.  ...  Butterfill for thoughtful comments and discussion during the development of this manuscript.  ...

Hand movement observation by individuals born without hands: phantom limb experience constrains visual limb perception

Marion Funk, Maggie Shiffrar, Peter Brugger
2005 Experimental Brain Research  
Increasing evidence suggests that the visual analysis of other people's actions depends upon the observer's own body representation or schema.  ...  Instead, neural systems matching action observation, action execution and motor imagery likely contribute to the definition of body schema in profound ways.  ...  We thank Marianne Regard for assistance in participant recruitments, Peter Roth for providing the drawings on the response sheets and Malgorzata Roos for statistical consulting.  ...

Emily Kilroy, Lisa Aziz-Zadeh
2017 Empathy - An Evidence-based Interdisciplinary Perspective  
Understanding other people's feelings and perspectives is an important part of effective social communication and interaction.  ...  Advances in neuroimaging technology have allowed social neuroscientists to study brain activity during this complex social process.  ...  Furthermore, one study found that observing a novel limb (the residual limb of an amputee) elicited more activity than observing a typical hand action.  ...

Crossmodal illusions in neurorehabilitation

Nadia Bolognini, Cristina Russo, Giuseppe Vallar
2015 Frontiers in Behavioral Neuroscience  
Such multisensory integration can dramatically alter the phenomenal experience of both environmental events and our own body.  ...  Such strategies involve rules for modulating experiential responses to multisensory information and rules that deal with important regularities (O'Callaghan, 2008) , as ways for coping with environmental  ...  Therefore, the use of tDCS as an add-on intervention to MBI could potentiate its antalgic action.  ...

How using brain-machine interfaces influences the human sense of agency

Emilie A. Caspar, Albert De Beir, Gil Lauwers, Axel Cleeremans, Bram Vanderborght, Jane Elizabeth Aspell
2021 PLoS ONE  
Brain-machine interfaces (BMI) allows individuals to control an external device by controlling their own brain activity, without requiring bodily or muscle movements.  ...  In particular, BMIs lack sensorimotor feedback, afford lower controllability and are associated with increased cognitive fatigue.  ...  FoA refers to a pre-reflective sensorimotor experience of being the author of an action, while JoA refers to the explicit declaration that an outcome was (or not) caused by our own actions.  ...
