The marine gastropod Aplysia offers two distinct advantages as an experimental preparation for studying cellular neuronal control of the circulation. First, its neurons are large in size and manageable in number, making it possible to identify single neurons as unique individuals that can be recognized in all members of the species. This feature allows one to work out neuronal networks in cellular detail. Second, there exists a significant body of data on the neural control of a variety of behaviors in Aplysia, including defensive withdrawal, locomotion, feeding, egg-laying, control of water balance, and respiration 28. Because circulatory function typically changes as part of an overall pattern of physiological adjustment, it is necessary to understand the control of all of the major organ systems in the body before one can fully describe the mechanisms and the nature of cardiovascular control. Although we are still a long way from such an understanding, a promising beginning has been made. The goal of this paper is to review the present state of our knowledge of the cellular and network mechanisms of cardiovascular control in Aplysia. The first part describes the circulatory system and the neurons that are known to affect it directly. The second part describes what is known about how the actions of these cells are integrated by the central nervous system during excretory, egg-laying, feeding, and respiratory behaviors. With a few exceptions, the work described below has been performed on A. cal (fornica.
