Microsaccadic inhibition and rebound after background luminance decreases between LLD and CTRL. (A) Dynamics of microsaccade rates following background luminance changes in different conditions in CTRL. (B) Dynamics of microsaccade rates following background luminance changes in different conditions in LLD. (C) Mean microsaccade rates in the inhibition epoch (60–330 ms) in the NoChange (no background luminance change) and Change (background luminance changes: Dark and Black) condition between LLD and CTRL. (D) Mean microsaccade rates in the rebound epoch (350 to 550 ms) in the NoChange and Change condition between LLD and CTRL. (E) Normalized microsaccade rate (Change minus NoChange condition) between LLD and CTRL. (F) Mean normalized microsaccade rates in the inhibition epoch in different conditions between LLD and CTRL. (G) Mean normalized microsaccade rates in the rebound epoch in different conditions between LLD and CTRL. In (A), (B) and (E), the shaded colored regions surrounding microsaccade dynamics curves represent the ± standard error range (across participants) for different groups. The gray area represents the epoch selected for analyses. In (C), (D), (F) and (G), the color-filled squares and error-bars represent mean value ± standard error (across participants) for each group, and the small circles represent mean value for each subject. Circle color dots represent each subject data point. CTRL: healthy age-matched older adults. LLD: late-life depression patients. Dark: 50% decrease in contrast relative to the gray background. Black: 100% decrease in contrast relative to the gray background. Bkgd: background. *Indicates differences are statistically significant.
