Figure 3. A) Correlation between differences in the first
derivative of pupil size changes and Von Frey tactile sensitivity
thresholds between body locations over time. B) Functional
uncorrected significance tests for these correlations. Thep -values are log-transformed, the ticks on the y-axis indicate
the respective steps. Both correlations between the finger and calf, and
the arm and calf reached statistical significance after about 0.5 to 0.6
s and lasted up to 0.7 s.
