Small knives made from broken razor blades (Pires and Hadfield. 1993) were used to remove the visceral mass and foot from these cold, anesthetized larvae. This cut (line A in Fig. 1 A) exposed the dorsal surface of the brain for extracellular recording, although it may have also eliminated pan of the pedal ganglia. The eyes and statocysts remained in this isolated head preparation. We also conducted experiments on animals from which only the visceral mass was removed (head-foot prepara- tions). Results were similar, but we have chosen to leave those data unreported because fewer controls were con- ducted. Initial activity patterns in all experiments were. B.
