Figure 6.
Color-coded minimum coefficient of variation (RTmin) of layer 2 as a function of the multiplexing parameters. Both layers 1 and 2 are intra-connected by electrical synapses. (A) Shows the enhancement performances of the electrical multiplexing (κm,e, τm,e). For optimized SISR in layer 2, we need either a shorter τm,e and stronger κm,e; or a longer τm,e and a weaker κm,e. (B) Shows the enhancement performances of inhibitory chemical multiplexing (κm,c, τm,c). For optimized SISR in layer 2, we need a stronger κm,c and a very long τm,c. (C) Shows the enhancement performances of excitatory chemical multiplexing (κm,c, τm,c). For optimized SISR in layer 2 we need very short τm,c and stronger κm,c. Parameters for layer 1, we need N = 25, n1,e = 1, β = 0.75, ε = 0.0005, α = 0.5, κ1,e = 0.1, and τ1,e = 1.0. Parameters for layer 2, we need N = 25, n2,e = 1, β = 0.75, ε = 0.0005, α = 0.5, κ2,e = 1.0, and τ2,e = 10.0.
