Experimental design and brain activity. (A) Example stimuli of hands, cosmetic and active prostheses, and objects. Participants’ own prostheses were included (‘own’ condition) as well as prostheses from other participants (‘other’s’ condition). (B) Stimuli were presented in an event-related design, involving a one-back recognition task. (C and D) Whole-brain activity maps for (C) hands and (D) active prostheses versus objects across all participants. Prostheses images activated lateral occipito-temporal cortex, partially overlapping with hand-selective activity. CS = central sulcus; R/L = right/left hemispheres; STS = superior temporal sulcus. (E) Prosthesis users (n = 26) show stronger activity than controls in response to active prostheses in the visual hand area. COPE = contrasts of parameter estimates. Error bars indicate SEM. *P = 0.008.
