   What is a chimera state?

   • The dynamical systems framework of chimera states offers a powerful tool to study the evolution of coherent and incoherent dynamics in oscillating systems such as the brain. A chimera state emerges when a system of oscillators evolves into two subsets of mutually coherent and incoherent populations ( 7 ).

   Do chimera states exist together with incoherent and coherent states?

   • To verify the existence of chimera states together with incoherent and coherent states in coupled systems, we compute the long time averaged mean phase velocity of each neuron defined as (8) ω i = 2 π M i Δ T, i = 1, 2,..., N, where M i is the number of spikes of the i th neuron during a sufficiently long time interval Δ T.

   How many communities are there in a chimera state?

   • In case of a coherent state, we observed only one community, and in case of a metastable state, we observed nine separate communities, each representing a cognitive system. For chimera states, communities with different distributions of cognitive systems emerged.

   When is Chimera state possible?

   • It has been demonstrated that the chimera state is possible only when the regular coupling topology is in nonlocal format. Taking only electrical synapse in nonlocally coupled neuronal network, chimera states are observed in Hindmarsh–Rose and FitzHugh–Nagumo models .
