Axial slice (y = 12) showing the result of the searchlight analysis. Peak coordinates; left nucleus accumbens (x = −8, y = 16, z = 0, 55 voxels, average r at the peak = 0.089) and right nucleus accumbens (x = 8, y = 16, z = −6, 63 voxels, average r at the peak = 0.109). Colors represent t values based on one-sample t-test testing the strength of the correlation between High Monetary Reward and High Social Reward-Self conditions. Note that the left nucleus accumbens area slightly overlaps (i.e. 9 voxels) with the left caudate ROI (Figure 1).
