Fig 2 — (A-D) ACh-controlled deformation of the attractor landscape. When ACh is released, the inhibition rate R_EI decreases because of disinhibition of inhibitory synapses projecting onto excitatory neurons. (A, C) Dynamics of the network with 16 modules with N_E = 1000 and N_I = 250 for (A) R_EI = 1.00 and (C) R_EI = 0.94. (B, D) The corresponding attractor landscapes. The red arrows show the typical transitive dynamics. The green arrows show the influence caused by the glutamatergic spike volleys with strength I_T. (E-H) Deformation of the attractor landscape caused by the bottom-up external inputs with strength I_B. (E, G) Dynamics of the network with 16 modules with N_E = 1000 and N_I = 250 for (E) I_B = 0.002 and (G) I_B = 0.006. (F, H) Corresponding attractor landscapes. The red arrows show the typical transitive dynamics.
