Bilateral regions of the ventral anterior and dorsal mid-insula (MI) are responsive to taste perception and viewing pictures of food. Univariate analysis results from both imaging tasks. (A) All tastes (sweet, sour, and salty) vs. the neutral tastant activated bilateral regions of the dorsal MI, as well as left ventral anterior insula (vAI) and right dorsal anterior insula (dAI). (B) All food vs. object pictures activated bilateral MI and ventral anterior insula, as well as left OFC (not pictured). (C) An overlap of the maps from A and B revealed bilateral ventral anterior and MI regions coactivated by food pictures and taste.
