Cortical areas used in the copying of Japanese ideographic characters and syllabic characters were studied using functional magnetic resonance imaging in healthy volunteers. Complexity of characters was controlled to illustrate differences resulting from character to sound conversion differences between the ideographic and syllabic characters. Statistical comparisons indicated extensive activation in the fusiform gyrus, posterior portions around the intraparietal sulcus and in the conjunction area of BA 6, 9 and 44 (which is assumed to be Exner's area) during the copying of ideographic characters. These findings suggested that indirectness between ideographic characters and their pronunciation demands extra processing such as semantic mediation and intensive grapheme processing in comparison with syllabic characters.
在健康志愿者中，使用功能磁共振成像研究了复制日文表意文字和音节文字时所使用的皮质区域。对文字的复杂性进行了控制，以说明表意文字和音节文字在字符到语音转换差异方面所产生的不同。统计比较表明，在复制表意文字时，梭状回、顶内沟周围后部以及BA 6、9和44的联合区域（假定为埃克斯纳区）有广泛激活。这些发现表明，与音节文字相比，表意文字与其发音之间的间接性需要额外的处理，如语义中介和密集的字素处理。
