The human visual system must employ mechanisms to minimize informational redundancy whilst maintaining that which is behaviorally relevant [1,2]. Previous research has concentrated on two-point correlations via spatial frequency and orientation tuning. Higher-order correlations are less studied, but they may inform us about cortical functioning [3].(More)
Research on single striate cortical neurons has often concentrated on their responses to stimuli defined by two-point correlations. Texture discrimination studies using a relatively small palette of isotrigon textures have indicated that we are sensitive to third and higher-order spatial correlations. To further evaluate the underlying mechanisms of texture(More)
