A Brain Mapping Approach to Inspect the Underlying Neural Correlates upon Perceiving Persian Metaphors

Metaphors are frequently used in our daily life communications to comprehend and convey abstract concepts. Different neuroimaging studies also show a wide neural connection to metaphor perception. This study used a brain mapping setup (quantitative electroencephalography) to examine large-scale brain networks in participants when they were submitted to non-metaphorical sentences as compared to creative and conventional metaphorical phrases. To this end, 20 healthy right-handed individuals with Persian as their mother-tongue language consented to participate in the above language task. Having evaluated the functional connectivity across key cortical hubs, no significant or predominant role of the right hemisphere was observed upon comprehension of the conventional and creative metaphorical phrases. Rather, a wide interhemispheric functional connectivity is proposed to play a key part in the above task. Further understanding about the neural networks involved in the semantic processing of metaphors may potentially open new avenues to neural modulation in patients who find it challenging to comprehend figurative language or abstract metaphorical meanings (e.g. schizophrenics).
