Locations of injection. Rats were bilaterally implanted with 0.6-mm-diameter guide cannulae through which 0.3-mm-diameter injection cannulae were inserted. A, Typical tracks of guide and injection cannulae. B, Locations of tip of injection cannulae in the AIC and OFC. Plates are adaptations from the atlas of the rat brain (Paxinos and Watson, 2007). AID, Dorsal agranular insular cortex; AIV, ventral agranular insular cortex; DI, dysgranular insular cortex; DLO, dorsolateral orbitofrontal cortex; GI, granular insular cortex; LO, lateral orbitofrontal cortex; VO, ventral orbitofrontal cortex.
