Unformatted text preview: s, respectively. Spontaneous time evolution of the excitatory-inhibitory network that approaches a stationary state. The external inputs are always kept constant here. Another example that shows periodic oscillation of the excitatory-inhibitory network. All parameters are identical to those in the preceding example except that the value of the excitatory-to-excitatory synaptic connection (WEE) is stronger. Phase plane analysis The arrows indicate the velocity vector (dE/dt, dI/dt). Starting from any initial state, the time evolution of the state (E, I) traces a trajectory that follows the local direction of the velocity vector. Robust oscillation of the excitatoryinhibitory network implies the existence of a limit cycle in the...
