Temporal association in a network of neuronal oscillators

We investigate temporal association in a set of globally coupled neuronal o scillators, which retrieves time sequences of stored patterns. The asymmetr y-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 si mulations, we identify four different states: the memory-retrieval state, t he temporal association state, the mixed-memory state and the no-memory sta te, and obtain the corresponding phase boundaries on the plane of the asymm etry ratio and the coupling strength.
