Among the subdivisions of SN, only medial SNc significantly responded to value (gains > losses), and this was significantly greater than the other two subdivisions (p<0.001). However, all three subregions showed a significant response to salience (gains + losses) (p<0.0001). Ventral striatum and vmPFC both significantly responded to value (p<0.0001), but only vmPFC was deactivated by salience. Meanwhile, anterior insula and dorsal anterior cingulate cortex only significantly responded to salience. Overall, only mSNc, VS and vmPFC showed significant BOLD response to value, while all regions except VS responded to salience.
