“Healthy” operation in the network is the ability to switch from emotional to cognitive processing. (A) We simulated a task composed of (1) 10-s resting epoch, (2) 15-s SP epoch (vACC received 3 brief stimulus every 5 s), (3) 15-s WM epoch (dlPFC received 3 brief stimulus every 5 s), and (4) 20-s resting epoch. Stimulation pulses were 250 ms long Poisson trains at 200 sp/s impinging on AMPARs with conductance 2.4 nS. (B) Sample activity in 4 neurons of each network in one simulation. In black, vACC neurons and in gray, dlPFC neurons. (C) Histograms of average population activity in each network during one task simulation. Upper panels correspond to dlPFC activity (gray) and lower panels to vACC activity (black). (D) Local field potentials (LFP) normalized power spectrum for the activated state. In both subnetworks (vACC and dlPFC), spectra are characterized by the coexistence of theta (2–8 Hz) and beta/gamma (12–50 Hz) synchronization. Jackknife error bars around the mean mark the 95% CI.
