The mouse PFC can be divided into the anterior cingulate cortex (green), PL (gray), IL (purple), medial oPFC (yellow), ventrolateral oPFC (blue), and lateral oPFC (orange). The agranular insula, often studied in concert with the lateral oPFC, is lateral to the lateral oPFC. Regions outlined on coronal images from the Mouse Brain Library (Rosen et al., 2000).
