This remarkable study suggests, perhaps for the first time, that the orbitofrontal cortex (OFC) imposes “its” values to other value-coding brain regions (e.g., dorsal striatum) to guide choice and preference. Under normal circumstances, the values of hierarchically lower brain regions are in line with those of the OFC and no conflict arises. However, when these values diverge, the OFC would take the lead and impose “its” values to guide behavior, even if they are less accurate or up-to-date than those of hierarchically lower brain regions. A key challenge for future research will be to better understand how and under what circumstances the OFC acquires a set of values that diverges from reality and from that acquired by other brain regions.
