title: Kanji word reading process analysed by positron emission tomography.
abstract: Positron emission tomography, involving the H2(15)O injection technique, was used to study changes in regional cerebral blood flow during Japanese kanji word reading. Three-times intrasubject averaging analysis revealed that the main cortical responses occurred in the bilateral (left-side dominant) posterior inferior temporal area for visual input. We believe the left posterior inferior temporal area processes highly complex morphological features of kanji. For language output, left-side dominant activation of the posterior inferior frontal gyrus and the basal ganglia was found.
