Axonal Noise as a Source of Synaptic Variability
Figure 2
Random variability of AP waveform in thin axons (d = 0.2 µm) of four different types.
Subfigures display data for N>200 single APs triggered by identical stimuli and initial conditions (thick circle, 1×SD; dotted circle 3×SD). (A) Distribution of AP width and (B) AP height for rat hippocampal interneuron model axon. (C) Distribution of AP width and (D) AP height for C-fibre axons. (E) Distribution of AP width and (F) AP height for squid giant axons with Patlak channels. (G) Distribution of AP width and (H) AP height in squid giant axons.
