Objective: The present study explored the eff ect of lateralized left-right resting brain activity on prefrontal cortical responsiveness to emotional cues and on the explicit appraisal of emotions based on their valence. Indeed subjective response to diff erent emotional stimulus should be predicted by brain resting activity and should be lateralized and valence-related (positive vs. negative valence). Methods: Hemodynamic measure was considered (functional Near-Infrared Spectroscopy, fNIRS). Indeed hemodynamic resting activity and brain response to emotional cues were registered when subjects viewed emotional positive vs. negative stimuli (IAPS). LIR (lateralized Index Response) during resting state, LI (Lateralized Index) during emotional processing and SAM rating were considered. Results: Regression analysis showed the signifi cant predictive eff ect of resting activity (more left or right lateralized) on both brain response and appraisal (SAM) of emotional cues based on stimulus valence. Moreover, signifi cant eff ects were found as a function of valence (more right response to negative stimuli; more left response to positive stimuli) during emotion processing. Conclusions: Therefore resting state may be considered a predictive marker of the successive cortical responsiveness to emotions. Key message: The signifi cance of resting condition for the emotional behaviour was underlined.
