摘要：
The present study analyzed the functional activity of granular and agranular insular cortices in contextual specificity of latent inhibition using a conditioned taste aversion paradigm. c-Fos immunolabeling was examined in insular cortex in preexposed and no preexposed groups under similar and different context conditions. Result showed that the exposition to a novel taste increased c-fos activity in insular cortex. However, a context shift caused an increase in immunolabeling in animals preexposed to saccharine. These results suggest insular cortex is part of a complex system to evaluate taste-response, and it may read the meaning of taste stimuli depending on the context. (C) 2014 Elsevier Inc.
