Fig. 7. Neural images of a moving target. (A-C) Contour plots of the angular distribution of relative intensity from a 3.44° target, seen at the eye (A) and after blurring by male (B) and female (C) optics. Contour lines are spaced at intervals of 0.1. The lines on far right indicate half-width. (D,E) Snapshots of the distribution of photoreceptor voltage responses to the same target moving at 180 deg. s-1 from left to right as reconstructed for male (D) and female (E) retinas. Crosses indicate the current position of the target. (F,G) Sampled retinal images of the moving target for male (F) and female (G) retinas. Colour patches represent the instantaneous voltage responses of individual photoreceptors separated at angles appropriate for males (1.6°) and females (2.5°).
