Figure 9: (a) Biological disparity map of neurons in cortex of macaque monkeys evoked by stimuli with seven different disparities. The position of the two crosses is constant through all the images marked as (B)–(H) (adapted from [45]). (b) A small portion extracted from the obtained disparity map to show consistency with the recent physiological discoveries about the smooth change of stimuli preference (continuity) in topographic maps in the brain as shown in (a).
