Chimera states in a neuronal network under the action of an electric field

The phenomenon of the chimera state symbolizes coexistence coherent and incoherent sections a given population. This identified in several physical biological systems presents variants, including multichimera states traveling state. Here, we numerically study influence weak external electric field on dynamics network Hindmarsh-Rose (HR) neurons coupled locally by an electrical interaction nonlocally chemical one. We first focus phenomena multicluster oscillating breathers that appear field's absence. Then presence, highlight presence state, alternating chimera.
