All parameters were measured separately in low and high SF domains defined in Materials and Methods; values are mean ± SEM. When making predictions, the low and high SF domains share the same contrast tuning parameters (average of the two domains). Measurements of SF and contrast parameters were made in three independent experiments, and measurements of TF parameters were made in two experiments.
