A. Schematic illustration of the network topology. E₁ and I₁ represent excitatory and inhibitory neuronal populations of network 1, receiving input from an external population X₁. Same for network 2. Coupling of neuronal populations is indicated by the arrows, synaptic strengths by the J_yz. B. Schematic illustration of the resulting activity in the network for constant stimulus X₁ and varying stimulus X₂. In this model we observe the activity of network 1 being suppressed when activity in network 2 increases. Colors of lines represent the population corresponding to panel A.
