Fig. 6From: Altered excitability of small cutaneous nerve fibers during cooling assessed with the perception threshold tracking techniqueIonic currents during an action potential generation. The extracellular field was altered for 1 ms with a bounded exponential shape. The figures to the left represent the simulation performed at 32 °C and to the right when the temperature is slowly decreased to 20 °C. a Membrane potential recorded at the distal end of the axon model. b The slow ionic currents. c The fast ionic currentsBack to article page
