Effects of strychnine on the inspiratory-related fluorescence change. A–D From upper to lower, the data obtained from R1 to R52 and the leaky integrated C4 activity (C4). a, b Raw fluorescence changes from each region under control and strychnine, respectively. c, d Mean fluorescence change under control and strychnine, respectively. A Group of regions in which the amplitude of the mean inspiratory-related fluorescence change was > 6SD of the baseline under both control and strychnine. B, C Group of regions in which the amplitude was > 6SD of the baseline only under control or strychnine, respectively. D Group of regions in which the amplitude was < 6SD under both conditions. E Left panel, a fluorescence image from which the data of panels A–D were obtained. Right panel, the relative position of each region (R1–R52) to the left panel. Each region of each group in panels A–D is marked by an ellipse with red, blue, green, and black lines, and its region number is given inside or in the vicinity of the ellipse
