Fig. 2. Network combining emotional influences from the amygdala and OFC with the critic at the striato-thalamo-cortical loops. A and B denote two possibly competing ideas. Arrows denote excitatory signals, filled circles inhibitory signals. In the gated dipole, the node activities are denoted by x’s with + for “on” activities, – for “off” activities (see text), and depletable transmitter weights by z’s.
