✦ Synopsis

1. In order to investigate neural mechanisms underlying the switching from hovering-swimming to hunting behavior in the carnivorous mollusc Clione limacina, the innervation of the major muscle bands was studied. The destination of a majority of nerves was traced. 2. Nervous cells sending their processes in the sensory motor nerves were mapped using the retrograde transport of cobalt ions. 3. The combination of morphological investigation, with local extracellular stimulation of groups of cells in semi-intact preparations, provided a detailed description of the functional involvement of the majority of the neural elements in either type of behavior. As a result, detailed diagrams for intracellular investigation of participation of individual cells and functional groups were obtained.
