Histochemical properties of axons associated with the salivary apparatus of the cockroach, Nauphoeta cinerea.
A variety of techniques have indicated that dopamine is probably the neurotransmitter at the salivary gland of the cockroach, Nauphoeta cinerea (Olivier). It is known from a previous ultrastructural study that two types of axon are associated with the gland but it is not known which of these axons contain catecholamines. The present study, using permanganate fixation or incubation in 5-hydroxydopamine or 6-hydroxydopamine, shows that only one category of axon contains catecholamines.
