Abstract: 統合失調症における視覚過程のmagnocellular系機能不全について、心理物理的、生理心理学的分析による関連論文を展望し、知覚形成過程における役割を検討した。Magnocellular系機能不全は、自閉症等の発達障害でも指摘されており、統合失調症特有のものとはいえない。しかし発達期の知覚形成過程に共通の生物学的基盤をもつhigh-risk児に対して、早期支援のための有効な指標になりうると期待される。
Influences of magnocellular dysfunctions to visual perceptual formation processes for person with schizophrenia were discussed. It is suggested that negative symptoms of schizophrenia are associated with magnocellular dysfunctions. They may be responsible for perceptual experiences, feelings, and attention to various events in the daily lives of persons with schizophrenia. It is suggested furthermore that the high-risk state is associated with hyper functions of magnocellular pathway. They may indicate that the magnocellular dysfunction is a vulnerable index for schizophrenia. But dysfunctions of magnocelluar pathway are also indicated in autism, dyslexia and so on, so it is not intrinsic for schizophrenia. It is expected that the dysfunction is a probable index for high-risk state that will be common biological bases in visual perceptual formation processes for the developmental period. We may be able to use such an index for supporting of children with the covert high-risk state and their parents in their early lives.
