We introduced fNIRS signal because fNIRS signal have the advantage that there is no interference from electro-oculogram (EOG) signal. However, it has some drawbacks, i.e., it contains not only functional signals of the brain but also systemic physiological signals evoked by physiological changes and body motion. We evaluated a separation method based on differences in hemodynamic modalities and based on independent component analysis (ICA). We, then, propose a new method which combines the above two methods in order to compensate for the drawbacks of both the methods in a complementary style. The results showed that the proposed method could be removed various artifact which often contaminated fNIRS signals.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2012～2014;   課題番号：24560534;   研究分野：統計的生体信号処理;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/d/r/50278735.ja.html"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/d/r/90295577.ja.html"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"YOSHIDA, Hisashi"},{"subitem_text_language":"en","subitem_text_value":"KOHAMA, Takeshi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学生物理工学部; 教授"},{"subitem_text_value":"近畿大学生物理工学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University"},{"subitem_text_value":"Kinki University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田,  久"},{"creatorName":"ヨシダ, ヒサシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"小濱,  剛"},{"creatorName":"コハマ, タケシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_24560534seika.pdf","filesize":[{"value":"406.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_24560534seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3456/files/KAKEN_24560534seika.pdf"},"version_id":"e6fbebfa-891a-47ec-862f-7289dce0608d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"光トポグラフィー","subitem_subject_scheme":"Other"},{"subitem_subject":"BOLD効果","subitem_subject_scheme":"Other"},{"subitem_subject":"脳機能成分","subitem_subject_scheme":"Other"},{"subitem_subject":"全身性成分","subitem_subject_scheme":"Other"},{"subitem_subject":"アーチファクト除去","subitem_subject_scheme":"Other"},{"subitem_subject":"独立成分分析(ICA)","subitem_subject_scheme":"Other"},{"subitem_subject":"覚醒維持状態","subitem_subject_scheme":"Other"},{"subitem_subject":"認知タスク","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"光イメージングおよび多次元生体信号計測による覚醒維持状態の脳・生理機能解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"光イメージングおよび多次元生体信号計測による覚醒維持状態の脳・生理機能解析"}]},"item_type_id":"8","owner":"3","path":["2987","2988"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-10-30"},"publish_date":"2015-10-30","publish_status":"0","recid":"3456","relation_version_is_last":true,"title":["光イメージングおよび多次元生体信号計測による覚醒維持状態の脳・生理機能解析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:34:59.846322+00:00"}
