Figure 4. Relationship between changes in proprioceptive drift (ΔPD), changes in the subjective ownership rating of rubber hand (ΔOR), and changes in galvanic skin response (ΔGSR) with regression lines.

The yellow and blue circles indicate values in the wake and sleep groups, respectively. ΔOR during immediate training was significantly correlated with ΔPD during immediate training in both the wake (A) and sleep (B) groups. ΔGSR during immediate training was significantly correlated with ΔPD during immediate training in both the wake (C) and sleep (D) groups. However, ΔOR during delayed learning was only significantly correlated with ΔPD during delayed learning in the wake group (E).
