Synopsis

Keywords: Brain Connectivity, NeuroscienceBy combining hyperscan fMRI (hfMRI) and the facial action coding system (FACS), we introduce a new brain-behavior interaction analysis that can identify the underlying brain networks for perception and expression for different emotions during eye contact. It consists of three steps. 1) The affective facial muscle movements are encoded by facial action units (FAU) using FACS. 2) The specific emotional FAUs subserve the regressors for the univariant analysis on hfMRI data. 3) The brains’ activation maps are transformed into brain networks by multivariant analysis. It provides an approach to quantify affective interaction and emotional states.
