An antidromic impulse in an axon refers to conduction opposite of the normal (orthodromic) direction[citation needed]. That is, it refers to conduction along the axon away from the axon terminal(s) and towards the soma. For most neurons, their dendrites, soma, or axons are depolarized forming an action potential that moves from the starting point of the depolarization (near the cell body) along the axons of the neuron. Antidromic activation is usually induced experimentally by direct electrical stimulation of a presumed target structure[clarification needed]. Antidromic activation is usually used to confirm that a neuron being recorded from projects to the structure of interest.
