Suggests nonclassical neurotransmission in coronary arteries; leaves open its identity and human relevance pending targeted studies.
Transient depolarizations in guinea pig coronary arteries elicited by transmural stimulation exhibit properties of excitatory junction potentials but do not appear to be mediated by norepinephrine, acetylcholine, or ATP.
Keef et al. (1988) studied this question.
