Figure 5. — (a) The Movie Watcher's facial expressions as represented by the PC1 of facial AUs are applied as a modulator (covariate) of neural activity on the Face Watcher's fNIRS signals acquired while viewing the emotive face of the Movie Watcher (combined oxyhaemoglobin (OxyHb) and deoxyhaemoglobin (deOxyHb) signals). See electronic supplementary material, table S3 for cluster details. (b) The Movie Watcher's affect valence and intensity ratings applied as a modulator of neural activity of the Face Watcher's fNIRS signals acquired while viewing the emotive face of the Movie Watcher (combined OxyHb and deOxyHb signals). AG, angular gyrus; DLPFC, dorsolateral prefrontal cortex; FP, frontal pole; LOC, lateral occipital cortex; MTG, middle temporal gyrus; SMG, supramarginal gyrus; STG, superior temporal gyrus. See electronic supplementary material, table S4 for cluster details.
