| This thesis analyzes the dynamics of three nonlinear systems through their theoretical and experimental models. Two of them are used in neuroscience studies (Chua's circuit and Hindmarsh-Rose model ). In particular, the main contribution is based on figuring out how this type of systems get synchronized and the resonant effects that appear as a consequence of the interaction among them. We use master-slave and ring topology to couple these oscillatory systems in unidirectional (or bidirectional) diffusive manner. On one hand, we numerically simulate a general system compound of oscillators. We extract time series, for their statistical analyses, in order to ?figure out not only what kind of synchronization exists among them but also if any of them exhibits some resonance effect. On the other hand, we design the electronic circuit associated with the general system, mentioned on top, for checking how robust the results are. Following this research line, we ?nd the experimental evidence of the appearance of order in a chaotic system under the in influence of a chaotic signal. Moreover, we also run into bistability in a master-slave neural system. Finally, we developed a visual application to show the dynamics of two electronic neurons connected by chemical and electrical synapse. | |
