Table 6. Total effects, direct effects and residuals (PSI values) for the functional neural network model of fear renewal.

Total effects are the algebraic sum of the direct and indirect effects. Direct effects represent the influence of one brain region on another with the impact of other regions left constant. Residual influences include the combined influences of areas outside the model and the influence of a brain region upon itself. The columns list origins of effect and the rows list structures being affected. Values given are coefficients for total, direct and residual effects. Effects that can not occur given the direct anatomical connections are left blank.
