Figure 1.
Number of reports on OFC in all species. PubMed search terms “OFC,” “Orbitofrontal Cortex,” and “Orbital Prefrontal Cortex” from 1948 to 2014. The steepest rise in the number of publications occurred in the early 2000s, which was preceded by a more gradual increase in the 1990s. Rat studies, although increasing in number over the past decade, still account for a minority of reports on OFC.
