This is well established at the kinematic level. I used functional\u003cbr /\u003eMRI (fMRI) to evaluate the neural substrates of the stability of mirror-symmetrical\u003cbr /\u003ebimanual movement. Right-handed participants (\u003ci\u003en\u003c/i\u003e= 17) rotated disks with their\u003cbr /\u003eindex fingers bimanually, both in mirror-symmetrical and asymmetrical parallel\u003cbr /\u003emodes. I applied the Akaike causality model to both kinematic and fMRI time-series\u003cbr /\u003edata. I hypothesized that kinematic stability is represented by the extent of neural\u003cbr /\u003e\"cross-talk\": as the fraction of signals that are common to controlling both hands\u003cbr /\u003eincreases, the stability also increases. The standard deviation of the phase difference\u003cbr /\u003efor the mirror mode was significantly smaller than that for the parallel mode, \u003cbr /\u003econfirming that the former was more stable. I used the noise-contribution ratio\u003cbr /\u003e(NCR), which was computed using a multivariate autoregressive model with latent\u003cbr /\u003evariables, as a direct measure of the cross-talk between both the two hands and the\u003cbr /\u003ebilateral primary motor cortices (M ls).The mode-by-direction interaction of the\u003cbr /\u003eNCR was significant in both the kinematic and fMRI data.

The asymmetric interhemispheric interaction from the left\u003cbr /\u003eM l to the right M l during symmetric bimanual movement might represent\u003cbr /\u003ecortical-level cross-talk, which contributes to the stability of symmetric bimanual\u003cbr /\u003emovements.", "subitem_description_type": "Other"}]}, "item_1_description_18": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_1_description_7": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "総研大甲第1205号", "subitem_description_type": "Other"}]}, "item_1_select_14": {"attribute_name": "所蔵", "attribute_value_mlt": [{"subitem_select_item": "有"}]}, "item_1_select_8": {"attribute_name": "研究科", "attribute_value_mlt": [{"subitem_select_item": "生命科学研究科"}]}, "item_1_select_9": {"attribute_name": "専攻", "attribute_value_mlt": [{"subitem_select_item": "20 生理科学専攻"}]}, "item_1_text_10": {"attribute_name": "学位授与年度", "attribute_value_mlt": [{"subitem_text_value": "2008"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "MAKI, Yoko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "0", "nameIdentifierScheme": "WEKO"}]}]}, "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": "simple", "download_preview_message": "", "file_order": 0, "filename": "甲1205_要旨.pdf", "filesize": [{"value": "309.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 309800.0, "url": {"label": "要旨・審査要旨", "url": "https://ir.soken.ac.jp/record/1198/files/甲1205_要旨.pdf"}, "version_id": "f0461c24-c522-4a30-b95e-c69d0b2738f8"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-02-17"}], "displaytype": "simple", "download_preview_message": "", "file_order": 1, "filename": "甲1205_本文.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "本文", "url": "https://ir.soken.ac.jp/record/1198/files/甲1205_本文.pdf"}, "version_id": "c2399895-d8fc-4f35-955b-1cde73441bfe"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Asymmetric control mechanisms of bimanual coordination: an application of directed connectivity analysis to kinematic and functional MRI data", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Asymmetric control mechanisms of bimanual coordination: an application of directed connectivity analysis to kinematic and functional MRI data"}, {"subitem_title": "Asymmetric control mechanisms of bimanual coordination: an application of directed connectivity analysis to kinematic and functional MRI data", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "1", "path": ["22"], "permalink_uri": "https://ir.soken.ac.jp/records/1198", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-02-22"}, "publish_date": "2010-02-22", "publish_status": "0", "recid": "1198", "relation": {}, "relation_version_is_last": true, "title": ["Asymmetric control mechanisms of bimanual coordination: an application of directed connectivity analysis to kinematic and functional MRI data"], "weko_shared_id": -1}
