title: Proctolin-like immunoreactivity in dorsal paired median neurons generating plateau action potentials in cockroach Periplaneta americana.
abstract: The proctolinergic nature of dorsal paired median (DPM) neurons generating plateau action potentials (PAPs) of the cockroach CNS has been demonstrated using a double labelling technique (lucifer yellow staining and proctolin-like immunochemistry). Electrophysiological results support morphological evidence that a direct pathway exists from axons passing throughout the proctodeal nerves to electrically active DPM neuron somata. However, the occurrence of spike failure along the neuritic membrane and the existence of a neuritic spike initiating site has been postulated because spontaneous PAPs recorded intracellularly were not associated on a one-to-one basis with peripheral axon spikes.
