Figure 3From: Impaired social brain network for processing dynamic facial expressions in autism spectrum disordersModels and results of dynamic causal modeling (DCM) regarding the mirror neuron system (MNS). A. Analyzed brain regions rendered on the spatially normalized brain. V1 = Primary visual cortex; MTG = Middle temporal gyrus; IFG = Inferior frontal gyrus. B. Analyzed models. Thin arrows indicate intrinsic connections between brain regions. Bold arrows indicate the modulatory effects of dynamic presentation. C. Mean coupling parameters (± SE) for the control (CON) and autism spectrum disorders (ASD) groups. Statistical comparisons showed that all parameters were significantly weaker in the ASD than in the control group (t-test, p < .05).Back to article page
