Consistent with gain anticipation, the slope of the activation for increasing losses was significantly greater than the slope of the deactivation for increasing gains. Loss aversion refers to our tendency to strongly prefer avoiding losses over acquiring gains. fMRI test measuring neural responses in striatal, limbic and somatosensory brain regions help track individual differences in loss aversion.
