Subnetworks and connections between them to form the full network.

<p>The subnetworks are comprised of either excitatory or inhibitory neurons. Subnetworks <i>B</i>₁ and <i>B</i>₂ consist of neurons of the same type, either excitatory (the EEI scenario) or inhibitory (the EII scenario). The subnetwork <i>A</i> has neurons of the opposite identity. For excitatory (inhibitory) <i>B</i>₁ and <i>B</i>₂, we arrange <i>w</i> ≥ 1 (<i>w</i> ≤ 1).
