Figure 6

Representative observation signals. A rest (white background) and a pinching (gray background) test trial are shown. The red vertical line at t=0 represents the stimulus onset when the subject started pinching isometrically, T _Δ is the shift of 5 seconds that was applied for the extraction of observations. O_{M 1}, O _{P M v} : fNIRS observations of data from M1 and PMv, respectively. O _{B R} , O _{H R} : observations of breathing and heart rate, respectively. O _{S C R} : observation of skin conductance response. O _{B P} : observation of blood pressure signal. Note that all observations are unit-less due to the normalization steps in the pre-processing.
