| Research Abstract |
In this study, we investigated the neural substrates involved in the figurative language comprehension such as metaphor and irony using functional MRI. The results showed that the metaphoric sentences in contrast to literal sentences elicited the higher activation in the left inferior frontal gyrus (IFG : BA45), medial prefrontal cortex (MPFC : BA9/10) and temporal regions. In the irony comprehension, activation in the bilateral frontal regions (IFG, MPFC) and superior temporal regions was shown. Our results suggest that activation in these regions might be affected by higher-order cognitive operations.
