Full body brain computer interface
Body Perception & Self-Consciousness
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
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?

Monkey avatar
Body Perception & Self-Consciousness
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

1. 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
2. Gordon G. Gallup Jr. 1976, Absence of self-recognition in a monkey (Macaca fascicularis) following prolonged exposure to a mirror
3. Gallup, G. G., Jr., 1970. Chimpanzees: Self-recognition.4. Susan D. Suarez 1, Gordon G. Gallup Jr. 2, 1986, Social responding to mirrors in rhesus macaques

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