The length of the terminal branch affects the response to a capsaicin-like current. A–C, Simulated voltage-clamp recordings from a central terminal following stimulation of single terminal branches of different length [75 µm (yellow, A), 100 µm (green, B), and 175 µm (blue, C)], by a capsaicin-like current. Note that the firing depends on the lengths of the stimulated terminal branch.
