Abstract

FUNCTIONAL magnetic resonance imaging was successfully used to study the activation of the motor cortices during retrieval of Japanese ideogram, Kanji. The subjects performed Kanji completion tasks to generate a Kanji in response to an element which is always written first. In most of the subjects,the contralateral premotor cortex, the presupplementary motor area (pre-SMA) and the bilateral intraparietal sulcus were activated during retrieval of Kanji without actual writing nor intentional mental writing. Activation associated with actual writing was shown in the contralateral primary sensorimotor cortex and the SMA proper. These results suggested that retrieval ofKanji would share the neural basis of motor representation with writing ofKanji except for regions directly working for motor output.
