WebFor test stimuli we used matrix of Gabor grating. We used two types of 10 x 10 matrices with chaotic and ordered orientation of Gabor gratings. The size, brightness and contrast of the stimuli were identical. The chaotic and ordered patterns activated different brain areas.

In this figure, the textures are created by summing together a large number of randomly scattered Gabors. By changing the shape and size of the Gaussian multiplier function with the same sinusoidal grating, the tradeoff can be directly observed.
