9. Full body brain computer interface Our Goal: • Predict full body motion using cortical signals • Use it to control a monkey avatar • Use the monkey avatar as a feedback for the real monkey Body Perception & Self-Consciousness

10. Open questions • Is it possible to predict both upper limb and lower limb motor activity at the same time? • Is a BCI easier to control if the visual feedback reproduces 3D movement of the subject? • Does the VR based training facilitated the training for controlling neuroprosthetics?

11. Monkey avatar Body Perception & Self-Consciousness

12. What we know? • No evidence that Macaque recognize themselves in a mirror 1,2 • Social responses, as with chimpanzees3, are common4 • No literature on social responses when confronted to VR G.G. Gallup, Jr., L.B. Wallnau, S.D. Suarez, 1980 Failure to Find Self-Recognition in Mother-Infant and Infant-Infant Rhesus Monkey Pairs Gordon G. Gallup Jr. 1976, Absence of self-recognition in a monkey (Macaca fascicularis) following prolonged exposure to a mirror Gallup, G. G., Jr., 1970. Chimpanzees: Self-recognition. Susan D. Suarez1, Gordon G. Gallup Jr. 2, 1986, Social responding to mirrors in rhesus macaques (Macaca mulatta): Effects of changing mirror location, Body Perception & Self-Consciousness

13. What we want to record • Detect: Interest, curiosity, positive negative reaction • When facing: • Black screen (baseline) • Fixed avatar • Moving skeleton • Moving avatar • Facing (mirror) • Back (third person) Body Perception & Self-Consciousness

14. What we expect • The monkey will be curious • She will be attarct by the moving avatar and skeleton • Social behaviour only with the monkey avatar • The fact that she can control and have specific rewards, should keep curiosity longer than the mirror experiment (2 weeks) • Question: would she considered it as an extension of herself or a “slave” that she controls?
