Verified step by step guidance

Understand the context: Neurons communicate through electrical signals, which are crucial for transmitting information throughout the nervous system.

Identify the key terms: The problem mentions 'electrical current' and 'axon of a neuron', which are important in understanding neuronal communication.

Differentiate between the terms: Action potential, resting potential, graded potential, and synaptic transmission are all related to neuronal activity but have distinct roles.

Define 'action potential': It is a rapid rise and fall in voltage or membrane potential across a cellular membrane, specifically in neurons, that constitutes the electrical current traveling down the axon.

Conclude by associating the term: Recognize that the electrical current traveling down the axon is specifically referred to as the 'action potential', which is the correct answer in this context.
