Using RMI, our measure of relative motivation, to divide our participant population, we found significantly greater activation in several regions in the BM > BC contrast for our money group (N = 46) than in our candy group (N = 14). The table here corresponds to the statistical map presented in Figure 5. Cluster maxima are listed in bold. All coordinates listed are in MNI space.
