You are correct. And your definition is precise and easy to
Action potentials are called spikes because when you look at an
oscilloscope or chart display (at slow speed) each action potential is
a vertical line, a "spike", rising out of the baseline. A "train" is
a series or line of things arranged so that one comes after another.
So a spike train is just a series of action potentials along one axon
(or, possibly, along several axons in a nerve).
