Computed SGN spike conduction times with additional delay Δt per 1 µm soma diameter increase.

d1 and d2 represent peripheral and central axon diameters; nmsoma denotes the number of surrounding single membrane layers in the soma region including the pre- and postsomatic segments. t1, t2, t3 and t4 denote postsynaptic delay, spike conduction time in the peripheral axon, presomatic delay and spike conduction time in the central axon, respectively. t_total = t1+t2+t3+t4, Δt|dsoma+1 µm denotes the enlargement step of the presomatic delay when dsoma is 1 µm increased.

d1与d2分别代表外周轴突（peripheral axon）与中枢轴突（central axon）的直径；nmsoma指胞体区域（包含轴突前胞体段与轴突后胞体段）周围的单层膜层数。t1、t2、t3、t4依次代表突触后延迟、外周轴突内动作电位传导时间、胞体前延迟以及中枢轴突内动作电位传导时间。总延迟t_total = t1+t2+t3+t4；Δt|dsoma+1 µm 指当胞体直径dsoma增大1 µm时，胞体前延迟的增幅步长。
