Neurocognitive model of the emergence of ownership: First the visual resemblance of the prosthesis is compared to the persistent representation of how a biological limb should look like in the body model. Successively, the postural and anatomical feedback of the prosthesis properties are compared to the current estimated postural state of the body, stored in the body schema. The last step is the sensory integration of the remaining afferent feedback. If there is consistency in all three comparator stages, ownership arises, and it is later used to update the body representation
