The model can be considered as a dynamical system whose solution includes jumps depending on a condition related to the behavior of the trajectory. Although the solution is discontinuous, we can define the Poincare map as a synthesis of successive submaps, and give its derivatives for obtaining periodic points and their bifurcations.Using our proposed method, we clarify mechanisms of bifurcations among synchronized oscillations with phase-locking patterns by analyzing periodic solutions observed in a model of coupled Hodgkin-Huxley equations. Moreover we illustrate a mechanism of the generation of chaotic itinerancy or the phenomenon of chaotic transitions among several quasi-stable states, which corresponds to associative dynamics or memory searching process in real neurons, by the analysis of four-coupled Bonhoffer-van der Pol equations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"徳島医学会","subitem_publisher_language":"ja"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"00373699","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00102041","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"75172"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉永, 哲哉","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"1587","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2017-11-15"}],"displaytype":"detail","filename":"sam_59_4-5_228.pdf","filesize":[{"value":"221 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2003818/files/sam_59_4-5_228.pdf"},"version_id":"949e2acd-3089-4dd6-a82a-d39e3afa46f3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"coupled neuron model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"synaptic transmission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bifurcation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nonlinear dynamical system","subitem_subject_language":"en","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":"シナプス結合ニューロンモデルの分岐解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シナプス結合ニューロンモデルの分岐解析","subitem_title_language":"ja"},{"subitem_title":"シナプス ケツゴウ ニューロン モデル ノ ブンキ カイセキ","subitem_title_language":"ja-Kana"}]},"item_type_id":"40001","owner":"7","path":["1713853295607","1716424837683"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-11-15"},"publish_date":"2017-11-15","publish_status":"0","recid":"2003818","relation_version_is_last":true,"title":["シナプス結合ニューロンモデルの分岐解析"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2024-10-28T02:27:00.475615+00:00"}
