Research Abstract |
This study aims to elucidate neural substrates for onomatopoeia related to food texture. First, we examined if magnetoencephalography can detect the oral sense area in the cortex. We verified that the 20-ms latency cortical response of trigeminal somatosensory-evoked field components localized at the primary sensory cortex can serve as a robust neurofunctional marker for the lip sensation. Second, we explored neural representation for cortical processing of ABAB-type four-morae onomatopoeia, rich in Japanese vocabulary for texture expressions. We assessed cortical activity evoked by ABAB-type onomatopoeia using MEG. Source analyses using minimum norm estimation revealed stronger neural activity for ABAB-type onomatopoeia than ABCD-type control words at the third morae in the inferior parietal cortices. This suggests that the third morae in the onomatopoeia accelerated phonological and semantic processing of the words in these regions.
