研究了对称耦合混沌神经元阵列的混沌同步问题。通过将耦合系统的变分方程转化为块对角变分方程，导出了同步流形稳定性的判据，并给出了不同耦合情况下同步的临界耦合强度.作为示例，考虑了具有开放式（即链）、环、星星和全对全（即全局）耦合方案的HR神经元。结果表明，耦合机制在神经元的同步和信息传递中起着重要作用。
Chaos synchronization in an array of coupled chaotic neurons with symmetric coupling is investigated. A criterion for the stability of the synchronization manifold is deduced by transforming the variational equation of the coupled system into a block diagonal one, and the critical coupling strengths for synchronization in different coupled cases are given. As examples for illustration, the HR neurons with the open-ended (i.e. chain), ring, star and all-to-all (i.e. global) coupling schemes are considered. It is shown that the coupling scheme plays an important role in synchronization and information transmission of neurons.
