Neurons are connected in a multiplex network with two layers l = 1, 2. Neurons within a layer are coupled in a ring, while neurons in adjacent layers are connected only to their adjacent neurons. (A) Neurons within each layer are coupled in a ring and interact only with their nearest neighbors via electrical synapses (κ1,e, τ1,e, κ2,e, τ2,e); multiplexing between these layers, represented by the black vertical dashed lines, may occur via electrical (κm,e, τm,e) or (inhibitory or excitatory) chemical synapses (κm,c, τm,c). (B) Neurons within each layer are coupled in a ring and interact with nl,c nearest neighbors via inhibitory chemical synapses (κ1,c, τ1,c, κ2,c, τ2,c); multiplexing between these layers, represented by the black vertical dashed lines, may occur via electrical (κm,e, τm,e) or (inhibitory or excitatory) chemical (κm,c, τm,c) synapses. In both scenarios, an enhanced SISR in layer l = 1 is used to optimize a poor or non-existent SISR in layer l = 2 by variation of the time-delay coupling parameters within a population (κ1,e, τ1,e, κ2,e, τ2,e, κ1,c, τ1,c, κ2,c, τ2,c) and between populations (κm,e, τm,e, κm,c, τm,c).
