Fig. 4. — Effect of SCi inactivation on local luminance modulation. (A) Experimental paradigm. (B) Effects of lidocaine injection on pupil size following the patch presentation at an example site during preinjection, postinjection, or recovery period. (C and D) Effects of SCi inactivation on the normalized pupil diameter [differences between postinjection and preinjection (C) or recovery (D) trials] in the bright and dark condition at the same example site. (E and F) Summary of lidocaine injection effects collapsed across monkeys (n = 6) on (E) Post − Pre condition and (F) Post − Recovery condition. (G and H) Summary of injection effects on pupil size (300–580-ms epoch poststimulation), including two saline control injections (n = 2) on (G) postpre condition and (H) postrecovery condition. In B–F, the black bar on the x-axis indicates the time of patch stimuli. Symbols as in Fig. 1.
