Temporal association in a network of neuronal oscillators

We investigate temporal association in a set of globally coupled neuronal oscillators, which retrieves time sequences of stored patterns. The asymmetry-to-symmetry ratio in the synaptic coupling as well as the total strength turns out to play a major role in these phenomena. By means of numerical simulations, we identify four different states: the memory-retrieval state, the temporal-association state, the mixed-memory state and the no-memory state, and obtain the corresponding phase boundaries on the plane of the asymmetry ratio and the coupling strength.
