Abstract

The myelinated axon can be modeled by means of a distributed RGC circuit. The Green function of this model allows for a generic formulation of the internodal segment response to any kind of stimulus, and accounts for the delay of the action potential associated with this segment. The RGC model accuracy is comparable to that of a more complex electromagnetic model, and predicted delay agrees with experimental measurements.

摘要

有髓鞘轴突可以通过分布式视网膜神经节细胞（RGC）电路进行建模。该模型的格林函数允许对节间段对任何类型刺激的响应进行一般化表述，并解释与该节段相关的动作电位延迟。RGC模型的准确性与更复杂的电磁模型相当，且预测的延迟与实验测量结果相符。
