Project description
The experience of one’s body as one’s own starts in the brain
Cortical oscillations temporally bind different sensory stimuli into a multisensory representation of the physical self to generate the sense of body ownership. With the support of Marie Skłodowska-Curie Actions, the Binding the Self project will provide unique insights into the mechanism that binds bodily sensory information. The results will be useful for clinical conditions with an impaired body representation and for the field of brain-machine interfaces. Specifically, the project will combine psychophysical tasks with electroencephalography and brain stimulation. The project will shed light on the similarities and differences between multisensory integration occurring for external events and for own-body perception.
Objective
Binding the Self tests the idea that cortical oscillations temporally bind different sensory stimuli into a multisensory representation of the physical self to generate the sense of body ownership, i.e. the experience of one's body as one's own. The project combines psychophysical tasks with electroencephalography and brain stimulation, providing unique insights on the mechanism that binds bodily sensory information. Multisensory temporal integration of visuo-tactile signals is thought to occur within Individual Alpha frequencies (IAF), while integration of tactile stimuli occurs within Individual Beta frequencies (IBF). Stimuli are integrated when they fall within the same cortical cycle and segregated for different cycles; the speed of cortical oscillations is modulated by task demand: cortical frequencies decrease when the task requires temporal sensory integration compared with segregation. Here, my first objective is to show that individual temporal resolution of perception in simultaneity judgments correlates with temporal resolution of multisensory integration involved in body ownership, both when body ownership is induced by visuo-tactile signals and when it is induced by proprioceptive-tactile signals, without vision. Next, I will demonstrate if (i) the integration of visuo-tactile stimuli that underpins body ownership occurs within IAF and if (ii) IAF is modulated by simultaneity judgments, which require temporal segregation, or ownership judgments, which require integration. Finally, I will clarify if (i) IBF integrates tactile information to produce body ownership without vision and if (ii) IBF is differentially modulated by tactile simultaneity or ownership judgments. Binding the Self reveals the similarities and differences between multisensory integration occurring for external events and for own-body perception. Results have implications for clinical conditions with an impaired body representation and for the field of the brain-machine interfaces.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
