Adult rats receiving 1.5 Gy X-rays at embryonic day 15 (E15) showed significant learning deficit in water maze. According to the mean value of the swimming time, we categorized the irradiated adult rats into the following three groups: slightly damaged group, mildly damaged group and severely damaged group. Heterotopic cells appearing at abnormal places were prominently observed in the dorsal hippocampus of the severely damaged group with a remarkable learning disturbance, while no ectopia at the hippocampus was detected in the slightly damaged group. We conclude that the cognitive dysfunction induced by prenatal exposure to x-ray irradiation is probably due to a heterotopic disturbance of the hippocampus.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"51st Radiation Research Socirty's annual meeting","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takai, Nobuhiko"}],"nameIdentifiers":[{"nameIdentifier":"666067","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xue, Zhi Sun"}],"nameIdentifiers":[{"nameIdentifier":"666068","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ando, Koichi"}],"nameIdentifiers":[{"nameIdentifier":"666069","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Sentaro"}],"nameIdentifiers":[{"nameIdentifier":"666070","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高井 伸彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666071","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"孫 学智","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666072","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安藤 興一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666073","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 千太郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666074","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Heterotopic cells in the hippocampus induce learning deficit after prenatal exposure to x-rays","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Heterotopic cells in the hippocampus induce learning deficit after prenatal exposure to x-rays"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-05-26"},"publish_date":"2004-05-26","publish_status":"0","recid":"67785","relation_version_is_last":true,"title":["Heterotopic cells in the hippocampus induce learning deficit after prenatal exposure to x-rays"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:33:44.710548+00:00"}
