The second analysis examined the relationship between functional connectivity of NAcc and the delayed reward discounting gradient. Using the NAcc as a seed region, a voxel-wise correlation map was generated as follows: Fisher Z transformed correlation coefficients between the seed region and every other voxel in the brain was correlated with ln(k). The results of this approach were corrected for multiple comparisons and statistically significant correlations (p<0.05) are displayed in Figure 2.
