Responses to interleaved stimulation. (A) Illustrations of electrode configurations with vessel maps (top line) and corresponding subtracted changing areas calculated from stimulations with different conditions (bottom line). A: anterior; L: lateral. (B) Super pixel time courses of the different conditions. The solid lines were obtained from the red dots nearest to source electrodes indicated in (A) and the hollow ones (labeled “distant”) were obtained from the far-most dots in (A). (C) Maximum reflectance changes among all rats imaged. The three different conditions showed significant differences between each other. *: p < 0.01; ** p < 0.001. (D) Calculated changing area ratios of the different conditions. The pixels of the areas having more than 3‰, 5‰, 7‰ reflectance changes were counted, and the ratios were then calculated to the maximum value (3‰ at one pair electrode stimulation condition), respectively
