Brain dialysates were collected every 5 min duration before and after stimulus from the bilateral ventral hippocampal in the two developing conditions consisted of stage 3 and five consecutive stage 5(5*C-5) following kindling. Extracelluar GABA levels were increased gradually and came to be plateau at 15-20 min lasting for several hours after stimulus. The enhancement of GABA Ievel were 2.5-3.0 fold that of the baseline at 5*C-5, and while 1.5-2.0 fold increase at C-3. This result reveals that the amygdaloid kindling in rats was accompanied by a progressive, long-lasting, and stimulus-induced enhancement of extracellular GABA levels in the both hippocampl.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本脳科学会","subitem_publisher_language":"ja"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10033568","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03887448","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"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":"植田, 勇人","creatorNameLang":"ja"},{"creatorName":"ウエダ, ユウト","creatorNameLang":"ja-Kana"},{"creatorName":"Ueda, Yuto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鶴, 紀子","creatorNameLang":"ja"},{"creatorName":"ツル, ノリコ","creatorNameLang":"ja-Kana"},{"creatorName":"Tsuru, Noriko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"1-3a.pdf","filesize":[{"value":"405.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1-3a.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/1406/files/1-3a.pdf"},"version_id":"c0bb0131-94cd-4af5-89bc-e238066e515c"}]},"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":"キンドリングの刺激前後に於ける海馬内γ-アミノ酪酸の放出量の動態変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"キンドリングの刺激前後に於ける海馬内γ-アミノ酪酸の放出量の動態変化","subitem_title_language":"ja"},{"subitem_title":"Sequential changes of extracellular γ-aminobutyric acid concentration before and after convulsion in the amygdaloid kindling rats","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"5","path":["72","30"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-08-04"},"publish_date":"2009-08-04","publish_status":"0","recid":"1406","relation_version_is_last":true,"title":["キンドリングの刺激前後に於ける海馬内γ-アミノ酪酸の放出量の動態変化"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2024-01-30T04:20:58.667919+00:00"}
