Chronotype differences in the neural response to the anticipation (1A) and outcome (1B) of monetary reward. Results are based on two-tailed t-tests run in SPM8, covarying for the time of scan, and masked for regions of interest in the medial prefrontal cortex (mPFC) and ventral striatum (VS). Evening-types displayed less mFPC activity during reward anticipation compared to morning-types (1A). Evening-types displayed more VS activity during win outcome compared to morning-types (1B).
