Predictions of the model. A, The model predicts that the SCs between the flicker tag and the sender populations do not depend on the attention condition. The cone is centered around an assumed delay between flicker signal and input populations of 50 ms. B, The model predicts that the SC between sender populations [input Populations (InP)] and simulated receiver V4 activity is strong in the gamma range and modulated by attention. The cone is centered around an assumed delay of 10 ms between sender populations and V4. C, Gating strength expressed in terms of the gating ratio G in dependence on the parameter μ. μ Controls the randomness in the phase relationship between V4 and the input population representing the non-attended flicker signal. The model predicts that G monotonously decreases with μ. D, Predictions of the model for the attentional modulation of inter-areal gamma-band synchrony between sender populations and receiver population (synchronization ratio S) in dependence on the parameter μ.
