Nevertheless, the modern human diet consists more and more of thoroughly processed and cooked foods, which dramatically reduce the demand on the stomatognathic system. The consequences of such a change in alimentary habits are not fully understood. In this study we used three-dimensional jaw-movement tracking device and jaw-muscle electromyography (EMG) to analyze changes in masticatory function in mice fed liquid or solid diets after weaning, and the hypothesis that the daily diet of soft food prevents the development of masticatory function was examined. As a result, we found that 1) The capacity to discriminate consistency of food is reduced in mice raised on liquid diet. 2) Patterns of jaw movement trajectories and masticatory rhythm were extremely unstable in liquid diet mice. 3) Either the masticatory central pattern generator (CPG) or its peripheral feedback mechanisms may be underdeveloped in animals raised on soft foodstuffs, although the conversion from sucking to chewing is not prevented.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本顎口腔機能学会雑誌, 13(1), pp.2-10; 2006","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"64559","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Noriaki"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本顎口腔機能学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本顎口腔機能学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1047134X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13409085","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","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, 教明"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"110006153939.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110006153939.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16729/files/110006153939.pdf"},"version_id":"f8810499-e594-4468-9b78-2a638b411270"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"咀嚼","subitem_subject_scheme":"Other"},{"subitem_subject":"軟食","subitem_subject_scheme":"Other"},{"subitem_subject":"発達","subitem_subject_scheme":"Other"},{"subitem_subject":"顎運動","subitem_subject_scheme":"Other"},{"subitem_subject":"筋電図","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"成長期における咀嚼機能の発達と学習のメカニズム解明に向けた実験的アプローチについて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"成長期における咀嚼機能の発達と学習のメカニズム解明に向けた実験的アプローチについて"}]},"item_type_id":"2","owner":"2","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-08"},"publish_date":"2009-12-08","publish_status":"0","recid":"16729","relation_version_is_last":true,"title":["成長期における咀嚼機能の発達と学習のメカニズム解明に向けた実験的アプローチについて"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:38:52.258867+00:00"}
