Figure 4. Negative scotopic threshold responses. Electrophysiologic analysis was performed after 12 weeks of diabetes. Under scotopic conditions, responses to a range of dim flash intensities were recorded. Means and standard errors averaged over 10 mice per group are shown across intensities given in log scotopic troland-seconds. Gaussian fits to the results for each group are shown. The peaks, and their estimated standard errors, of these Gaussians are compared in the inset, with the significance (t test *, p<0.05) of the differences indicated.
