If you attach the electrode to your wrist, a steady line of spikes and swoops will appear. If you attach that same electrode to your houseplant’s leaf, and touch it in any way, a spike and swoop will appear on the readout that looks remarkably similar. These are the action potentials—little bursts of electricity—produced, in your case, by the neurons in your heart that are firing at regular intervals to
