TI  - Participation of the left posterior inferior temporal cortex in writing and 
      mental recall of kanji orthography: A functional MRI study.
PG  - 954-67
AB  - To examine the neuropsychological mechanisms involved in writing kanji 
      (morphograms), we used functional MRI (fMRI) in 10 normal volunteers, all 
      right-handed, native Japanese speakers. The experimental paradigms consisted of 
      kana-to-kanji transcription, mental recall of kanji orthography and oral reading 
      and semantic judgement of kana words. The first two tasks require manual and 
      mental transcription of visually presented kana words into kanji, respectively, 
      whereas the last two tasks involve language processing of the same set of 
      stimulus words without recall of kanji. The transcription and mental recall tasks 
      yielded lateralized activation of the left posterior inferior temporal cortex 
      (PITC). By contrast, neither oral reading nor semantic judgement produced similar 
      activation of the area. These results, in good accordance with lesion data, 
      provide converging evidence that the left PITC plays an important role in writing 
      kanji through retrieval of their visual graphic images, and suggest 
      language-specific cerebral organization of writing. The set of fMRI experiments 
      also provides new neuroimaging data on the cortical localization of basic 
      language functions in people using a non-alphabetical language.
