In order to analyze the dynamic behavior of neural systems such as oscillations or rhythms, an approach based on the dynamical systems theory may be useful. In the first part of this article, we present an elementary introduction to that approach based on the materials for an author's lecture. In the second part, we introduce our own study related to dopamine and reinforcement learning using that approach, in which we assumed the decay of learned values and propose a possible mechanism of the effects of dopamine depletion on motivation.
