Abstract
The spontaneous and light-evoked firing patterns of the compound action potentials (CAPs) in the isolated eye of Aplysia are experimentally observed from a control systems viewpoint. The eye, exhibiting an endogenous bursting activity and a marked circadian rhythm in darkness, is a self-excited system and responds to illumination with a controlled electrical activity. It is represented by the nonlinear systems model predicting the firing-rate variation of the CAPs. Construction of the model is based on the eye's biological model reported in the literature, and involves an experimental analysis of the system characteristics using linear approximation and conventional control systems techniques. The model is simulated and found to adequately conform to the observed behavior of the eye under various experimental conditions.
