USING ELECTROENCEPHALOGRAPHY (EEG) AND VIRTUAL REALITY (VR) TO UNDERSTAND &
Our approach enabled us to manipulate and measure the SoA
Questions currently investigated: Can we measure variations of the SoA in real-time? Do all the principles impact equally the SoA?

IV - Discussion
Replication of results from the literature [Schmidt et al., 2010; Tonin et al., 2013]
Questions currently investigated: Is this marker (LI) suitable for a neurofeedback training procedure?
Is it measurable on a single trial basis? Does it correlate with performance or expertise?
