弱耦合振荡器系统中的锁相可以通过检查相关系统来预测，其中耦合在振荡器周期上被平均。如果耦合较大，则此操作失败。结果表明，在大的相互作用的存在下，一对或一个链的振荡器可能会发展一个新的稳定的平衡状态，对应于振荡的停止。这种现象对于神经类型的相互作用是鲁棒的，并且不会发生在弱耦合的系统中。
Phase-locking in a system of oscillators that are weakly coupled can be predicted by examining a related system in which the coupling is averaged over the oscillator cycle. This fails if the coupling is large. It is shown that in the presence of large interactions, a pair or a chain of oscillators may develop a new stable equilibrium state that corresponds to the cessation of oscillation. This phenomenon is robust for neural type interactions and does not happen in systems that are weakly coupled.
