Phase-locking patterns underlying effective communication in exact firing rate models of neural networks
Fig 7
Effects of the disruptor on the E-cell evoked response for some representative trails.
Three different types of entrainment inside 1:1 phase-locking region corresponding to (A) T1/T* = 0.845, (B) T1/T* = 0.93 and (C) T1/T* = 1. (Top) Time evolution of the excitatory firing rate re for system (1)-(2) in the absence of perturbation (dashed yellow curve), when the network is entrained by the primary input (dashed-dotted orange curve) and when both the primary input and the distractor are present (solid red curve) for a time duration of 6T1. (Bottom) The primary input (solid black) and the distractor (dashed black) correspond to inputs of von Mises type with A1 = A2 = A = 0.1, κ1 = κ2 = 2 and a frequency relationship T2/T1 = 1.2. (D, E) Factors Δα, Δσ and describing changes in the E-cell evoked response for the case T1/T* = 0.845 (primary on the left-hand side of the Arnold tongue) and T2/T* = 1.2T1/T* = 1.04 (distractor on the right-hand side of the Arnold tongue) when (D) the amplitude of the primary A1 is varied from 0 to 0.2 while keeping the amplitude of the distractor fixed at A2 = 0.1 and (E) viceversa. We have computed the mean and standard deviation of these factors over 10 cycles of the primary input.
