“…The lack of amplitude doubling in the central region of the cell (Fig. 2D and data in [11]), where collision occurs, provided further evidence that two APs do not superimpose and penetrate. Interestingly, the multisensor arrangement also allowed to extract the pulse propagation velocities for the control and collision experiments.…”

“…Thus, additional control experiments were intermittently performed in course of an experiment in order to identify changes in pulse shape that are not due to pulse collision. These experiments revealed that broadening of an AP or small distortions can occur in absence of collision (see examples in [11]). Therefore, caution must be taken in order not to erroneously attribute such changes in pulse shape during a collision experiment to pulse penetration, etc.…”

“…1D). In none of the experiments conducted (N=26 in n=10 cells; data for all control and collision experiments are publicly available [11]), an additional discrete AP or "M"-shaped pulse appeared at the extremal sensors. In one of the cells, one external sensor recorded a broadened AP.…”

Background. It is a common incident in nature, that two waves or pulses run into each other head-on.The outcome of such an event is of special interest, because it allows conclusions about the underlying physical nature of the pulses. The present experimental study dealt with the head-on meeting of two action potentials (AP) in a single excitable plant cell (Chara braunii internode).Methods. The membrane potential was monitored at the two extremal regions of an excitable cell. In control experiments, an AP was excited electrically at either end of the cell cylinder. Subsequently, stimuli were applied simultaneously at both ends of the cell in order to generate two APs that met each other head-on.Results. When two action potentials propagated into each other, the pulses did not penetrate but annihilated (N=26 experiments in n=10 cells). Conclusions Graphical abstract Highlights-When two pulses meet, they reveal information about their physical nature.-Upon running into each other, two action potentials in an excitable plant cell annihilate -Action potentials in plant cells and nerves are similar nonlinear phenomena.
