Figure 13. Responses to figure and ground as a function of stimulus contrast.

A: Average firing rate to figure and ground. B: Modulation strength (figure minus ground responses). Grey squares represent the modulation strength for different figure-ground textures observed in visual cortex of monkeys. C: Onset latencies of figure-ground modulation. Grey squares represent onset latencies for different figure-ground textures observed in monkey visual cortex. The high contrast stimulus used by Supèr (Supèr et al., 2001) is set here to 100% for comparison.
