Chaotic regimes have been observed experimentally in neurons as well as in deterministic neuronal models. The bursting R15 cell in the abdominal ganglion of Aplysia has been the subject of extensive mathematical modeling. The model of Plant and Kim is capable of exhibiting both bursting and beating modes of electrical activity. We demonstrate (1) ...

Mathematical models of two Aplysia neurons simulate salient features of the electrical and chemical activity of these neurons. First, the endogenous burster R15 was modeled as a Hodgkin-Huxley (HH) type membrane equivalent circuit coupled to a fluid compartment model. The model simulates available data on potential and bulk $Ca\sp{2+}$ concentration ...
