Summary A long duration (over 30 ms), large amplitude (up to 1000 μV) action potential, was recorded by an extracellular electrode placed near the Y-organ, or molting gland, of the terrestrial isopod,Oniscus asellus. This action potential discharged in a slow tonic fashion (0.20–40.0 spikes per min), and eminated from the lateral nerve plexus (LNP), a neurohemal region believed to control, in part, the activity of the Y-organ. By correlating the rate of electrical activity of the LNP with the molt cycle, it will be possible to assess the role of these neurosecretory cells in regulating the production of ecdysone by the Y-organ.
