Input effects on the E-cell evoked response for a network entrained by coherent inputs.
(A) Evolution of the firing rate variables re (red) and ri (blue) of the perturbed system (1)-(2) with a von Mises input with κ = 2 (dashed green) for a representative periodic orbit within the 1:1 phase-locking region. (B-E) Factors describing changes in the E-cell response within this phase-locking region for orbits of the perturbed system (1)-(2) calculated along (equidistant) sections A = ct of the corresponding Arnold tongue, indicated by the color of the curve (ranging from dark blue, A = 0.01, to yellow, A = 0.2, with increments of size 0.01). The factors are: (B) Δτ, describing the timing between inhibition and input volleys (normalized by the input period T), (C) , describing the rate change in the averaged firing rate of the E cells, (D) Δα, describing the rate change in the maximum of the firing rate of the E cells, and (E) Δσ, describing the rate change in E-volley half-width.
