A population of neuronal oscillators globally coupled through a common buffer (a mean field) was analyzed using the Hodgkin-Huxley (HH) equations, which are famous as a single neuron model. In the system, it was observed that they oscillate in a phase-locked state very slowly compared with the inherent periods of each uncoupled neuronal oscillator or their firing are inhibited completely. However, the generation mechanism of these phenomena is not clear. In this study, a population of globally coupled neuronal oscillators is analyzed using the three dimensional Bonhoeffer-van der Pol equations, which are the simpler single neuron model than the HH equations. Similarly to the case of the HH equations, there are interesting phenomena such as very slow phase-locked oscillation (compared with the inherent periods of each uncoupled neuron oscillator) or the death of all oscillations. In particular, it may sound strange, but this slow phase-locked oscillation is caused by the existence of fast oscillators. We also analyze what interactions between neuronal oscillators generate this macroscopic biological rhythm. |
