Region-of-interest univariate analysis. Univariate value and saliency signals in the vmPFC and the ventral striatum, defined based on a recent meta-analysis of the valuation system20. In the vmPFC, there was a significant effect of value, but not saliency, while in the ventral striatum, the effects of both value and saliency were statistically significant (n = 18). Error bars denote SEM. NS not significant;+ p < 0.1; *p < 0.05; ***p < 0.001. vmPFC ventromedial prefrontal cortex
