Abstract

This postdoctoral project aims to study causal relationships between mathematical properties of synaptic current and the phase synchronization process in networks of coupled neurons. The neuron model used is derived from the Hodgkin-Huxley model, a traditional mathematical model that describes neuronal behavior through ionic currents. The study is made for conditions where neurons present a high degree of phase synch- ronization even considering weak coupling regimes (low-amplitude coupling currents). In these cases, the increase in the intensity of the coupling current desynchronizes the network, characterizing a non-monotonic evolution of the synchronization as a function of the coupling amplitude. The objective of this proposal is to evaluate how the mutual interactions between neurons lead the system to future synchronization states. (AU)
