Sense of body ownership and sense of agency are sensorimotor root of bodily self-consciousness. However, dynamics of their construction still remains unclear. Here, we immersed sixty participants into the VR environment and had them manipulate the avatar’s hand motions through the haptic device. Inserted visuomotor rotation disrupted the subjective score of body ownership and agency over the avatar but they recovered along with sensorimotor adaptation. To examine why their temporal profile of recovery were different, we dissociated the internal motor memories into the two components: fast memory and slow memory. We found that the recovery of body ownership was driven by fast memory and the recovery of agency was driven mainly by slow memory. Our results indicate that multiple motor memories underpin the basis of bodily self-consciousness and their difference of temporal dynamics originates from such motor memories with distinct time courses.
