The ovulation hormone of the pond snail Lymnaea stagnalis is produced by the caudo-dorsal cells (CDCs) of the cerebral ganglia [1]. The CDCs secrete their products (see also Geraerts et al., this volume) during a 30 min period of repetitive spiking activity termed the afterdischarge [2]. This discharge can be elicited by a sudden change of environmental conditions [3] and triggers a stereotyped pattern of overt and covert behaviors that result in the deposition of an egg mass containing ±100 eggs on a suitable substrate [4].
