From: An analysis of the dependence of saccadic latency on target position and target characteristics in human subjects

Figure 1

Comparison of saccades in response to a stationary target of normal intensity (left hand column) and of a reduced intensity red target (right hand column) for direct viewing in the same subject. A & B. Specimen saccadic recordings aligned to the same saccadic latency to show the progressive increase in saccadic amplitude for target displacements, from lower to upper traces, of 10; 15; 20; 24 & 28 deg. C & D. Saccadic amplitude against target displacement showing best fitting regression line (C: y = 1.31 + 1.04x; R2 = 94.8%, P slope < 0.001; F = 1454; d.f. = 79), D: y = 0.29 + 1.14x; R2 = 94.7%, P slope < 0.001; F = 1282; d.f. = 72). E & F. Saccadic latency against target displacement with dashed line showing mean value (E: R2 = 0.0%, P slope = 0.78, F: R2 = 0.0%, P slope = 0.67). G & H. Histograms of saccadic latencies from E & F, respectively. Mean ± S.E.M. are: (G) 226.4 ± 5.4 ms (n = 81), (H) 227.3 ± 4.1 ms (n = 71).
