Fig 6. The global potential landscape of the noisy mesocortical dynamics.

Fig 6

For the normal control parameters DA-releasability (RDA = 0.0058nM.ms−1) and D1R-sensitivity (D1Rsens = 3) of the mesocortical dynamics, the global potential landscape is shown over the aPN-D1Ract plane, along with its contour projection onto the plane. The system in sustained-firing state is depicted by a ball sitting in the corresponding basin of attraction whose depth provides the potential barrier (PB) restricting the noise-induced transition of the system to spontaneous-activity state. The contour projection illustrates the fluctuation size in the system state around its mean point, which governs the signal-to-noise ratio (SNR) of the cortical sustained activity facilitating WM maintenance.
