MVPAs reliably classify taste quality and food picture category within bilateral regions of the dorsal MI. Taste-responsive regions of the bilateral insula, which were identified using the same taste paradigm within an independent dataset (12), were used as regions of interest for multivariate classification analyses performed on both imaging tasks. Within the bilateral dorsal MI, we were able to reliably classify both taste quality and food picture category, whereas we could classify only tastes within dAI. We could not reliably cross-classify food pictures by training on tastes, or vice versa.
