Study locates brain areas for understanding metaphors in healthy and schizophrenic people

People with schizophrenia have often problems in understanding some common figurative expressions, such as humour, irony, and spoken metaphors. They tend to take the metaphor at its literal meaning (for example, “a leap in the dark” may imply jumping and darkness for someone with schizophrenia): it may take some time for them to arrive at an understanding of what the metaphor is meant to imply. There has been little attempt to understand why this might be so at a neurological level.
