Title: “The modular nervous system of hydroids & medusae: evolution of central control.”
Abstract: Even the relatively simple nervous systems found in the Cnidaria are capable integrating behaviour such that feeding is favoured over foraging and defence is favoured over feeding. Some Cubomedusae even exhibit courtship prior to mating (Lewis and Long, 2005). Such complexity might indicate a degree of central nervous control, but in fact separate nerve circuits appear to be responsible for each different activity. It seems that in its simplest form the cnidarian nervous system is organised in a modular fashion. The seminar will show how different modules interact and how in species such as Aglantha digitale, individual modules have evolved so as to share components."
