Conversely, when we tested for a correlation between BOLD activation and the RPE we found a significant effect in the ventral striatum (vStr) (Figure 3c), consistent with previous accounts (McClure et al., 2003; O’Doherty et al., 2003), but no effects for an SPE even at p < 0.001 uncorrected. The graph of the average PSC across subjects in this region shows the opposite pattern from that in the pIPS and latPFC: a linear increase in BOLD activity across trials with increasing RPE, but no such increase for the SPE.
