Comparison between electric thresholds of different nerves

Mean electric threshold	Description	Reference
ET = 301 ± 128 V/m	TvMS of one-dimensional neuronal culture.	This article.
ET ≈ 170 ± 20 V/m	Average threshold for electric stimulation of two-dimensional neuronal cultures in vitro (10 ms duration).	Breskin et al. (43).
ET ≈ 145 ± 90 V/m	Electric field threshold for magnetic stimulation of human motor cortex (from average motor threshold of index finger).	N. Levit-Binnun, personal communication, Physics of Complex Systems, Weizmann Institute of Science, 2006.
ET ≈ 130 ± 10 V/m	Average threshold for magnetic stimulation of a frog's sciatic nerve.	Rotem and Moses (42).
