Figure 3. (A) Cortical activation maps produced by inosine 5’-monophosphate (IMP), monosodium glutamate (MSG), and a combination of the MSG and IMP (MSGIMP) in the insula/operculum area, the orbitofrontal cortex (OFC), and the anterior cingulate cortex. (B) Timecourses of cortical activation to IMP, MSG, and MSGIMP in the OFC showing the supra-additivity effects of the combination of the MSG and IMP. Figures modified from De Araujo et al. (Citation2003) (De Araujo, Kringelbach, Rolls, and Hobden Citation2003) and reproduced with authors permission.
