Experimental setup and results from Longo et al. (2009) in which vision of the body was shown to be analgesic, subjectively (using self-report pain ratings) and objectively using laser-evoked potentials. (A) The mirror box technique in which the subject has the experience of viewing their right hand, while in fact seeing their left hand reflected in a mirror. (B) Laser-evoked potentials (left) and peak-to-peak amplitudes (right) for the three experimental conditions. Error bars are one SEM.
