The action potential (AP) is an electrical impulse elicited by depolarization of the neuronal membrane from the resting membrane potential (around-70 mV). It propagates along the axon, allowing for rapid and distant communication. Recently, it was claimed that two APs traveling in opposite direction will pass unhindered through each other (penetrate) upon collision [Gonzalez-Perez et al. Phys. Rev. X4, 031047 (2014)]. We tested this claim under carefully controlled conditions and found thatwe cannot reproduce penetration. Instead, APs consistently annihilated upon collision. This is consistent with a vast body of literature.
