✦ Synopsis


This paper deals with a model describing the behavior of barium-treated Apalysia neurons. The model is represented by a dynamical system, so-called "complete system", defined in R 4 and depending on a small parameter. The study of this system under zero membrane current conditions was performed with the use of the qualitative theory of singular perturbations. We show that this system has a stable periodic solution of the discontinuous type when the small parameter tends to 0 +. A reduced system defined in R 3, associgted to the complete system was also studied: it corresponds to a constant activation of the inward current. We demonstrate that the corresponding hypothetical cell remains silent under zero current conditions.
