The KIV model of the limbic system, consisting of two KIII’s and one KII (Myers et al. 2008). Feedforward (Wff1, Wff2, Wff3) and Feedback (Wfb1, Wfb2, Wfb3) weights can be adjusted within each network of the KIV. External weights (WA, WB, WC) and can be adjusted to determine the level of influence the independent networks have on the entire system
