Fig. 3From: Altered excitability of small cutaneous nerve fibers during cooling assessed with the perception threshold tracking techniqueThe effect of cooling the skin on the perception threshold. The experimental result of perception thresholds to electrical currents delivered to the skin with temperature regulated to 20 °C or 32 °C. Data is shown as mean and standard error. Statistically significant differences between the two temperature conditions are indicated by asterisks, ***p < 0.001, Sidak multiple comparisonsBack to article page
