Fig. 9. Pre-ecdysis and ecdysis burst patterns in the isolated central nervous system (CNS) of pharate larvae in vitro. (A) Ecdysis-triggering hormone (ETH)-induced asynchronous pre-ecdysis II bursts in ventral nerves of abdominal ganglia 4-6 (AG4-6V). (B,C) Ecdysis bursts in dorsal nerves of abdominal ganglia 2-5 (AG2-5D). Note that ETH-induced ecdysis burst patterns (B) are very similar to natural ecdysis bursts (C). Calibration bars: horizontal, 5 s; vertical, 10 µV.
