WM operations for a heuristic firing rate model.

The results of two experiments are reported here for different background currents: WM maintenance via spontaneous reactivation of the target population (I_B = 1.520, A) and via a persistent asynchronous activity (I_B = 2.05, B). Profiles of the stimulation current for the excitatory populations (A1-B1). Population firing rates r_k(t) (A2-B2), local field potentials LFP_k defined in Eq (28) (A3-B3), normalized available resources (A4-C4) and normalized utilization factors (A5-C6) of the excitatory populations calculated from simulations of the firing rate model (19), (21). Spectrograms of the local field potentials: LFP₁(t) (A6-B6), LFP₂(t) (A7-B7), and LFP₀(t) (A8-B8). All the other parameter values as in Fig 3.
