Fig. 5.  Effect of visual information. (A  and B ) Response times (A ) and corresponding proportion of correct responses (B ) given by subjects before deafferentation (control), during upper limb anesthesia without visual access to the deafferentated limb (RA), and during upper limb anesthesia with the deafferentated limb visible (vision). The averages for the six natural and six unnatural orientations are presented for each view. Error bars  represent SDs. ANOVA main effect of condition (control, RA, or vision) was significantly different for both proportion of correct responses (F^2,36= 102.7, P < 0.0001) and responses times (F^2,36= 118.3, P < 0.0001). RA = regional anesthesia.
