(a) The endogenous connection among the selected ROIs. (b) Winning model for modulations evoked by facial expressions on the connections between the amygdala and inferior temporal (IT) cortex (TEO and TE). (c) Winning model for modulations evoked by facial expressions on the connections between OFC, the amygdala, and IT cortex (c). (d) Winning model for modulations evoked by facial expressions on the connections between VLPFC, the amygdala, and IT cortex. Red lines show the endogenous, known anatomical connections (Matrix A). Black lines show the modulatory effects evoked by emotional facial expressions between the amygdala and IT cortex (Matrix B). Green lines show the modulatory effects on connections among OFC, VLPFC, the amygdala, and IT cortex evoked by facial expression. Blue lines show the input into the system (Matrix C).
