Fig 5. HKB model with an added exit-from-synchrony term shows entry and exit-from-synchrony.

Fig 5

(a) Original HKB model of Ref [26] converges to synchrony and stays locked in a periodic synchronized motion. ω1 = 1.5, ω2 = 1, ϵ = −1, β = 0.5, δ = 1, α = 4, γ = 1, v1(0) = 2, v2(0) = 1, x1(0) = x2(0) = 0. (b) Modified HKB model according to Eqs 13 and 14, with exit-from-synchrony term, shows entry and exit-from-synchrony and complex non-periodic motion. Parameters are the same as in a), with exit-from-synchrony parameters β1 = β2 = 3, τ = 1, E0 = 0.04, ϵ0 = 0.001, η = 2.
