The hypothetical time comparison circuit consists oftwo types of time-coding neurons and a small cell, to which the two time-coding neurons converged. Here I studied the type of synaptic transmission in the time-coding circuit in two species. I immunohistochemically found that one of the inputs of the time-coding neuron is inhibitory in Gymnarchus (mormyriform). However, in Brachyhypopomus (gymnotiform), conventional electron microscopy showed that both inputs are excitatory. This comparative analysis revealed that the topologies of time coding neurons are identical in all major groups of other weakly electric fishes so far studied. However, the modes of synaptic transmission to the small cell, a time comparator, are different between species.","subitem_description_type":"Abstract"}]},"item_2_description_18":{"attribute_name":"科研費研究者番号","attribute_value_mlt":[{"subitem_description":"50450416 | https://kaken.nii.ac.jp/ja/search/?qm=50450416","subitem_description_type":"Other"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"科学研究費補助金研究成果報告書\n研究代表者：松下 敦子［総合研究大学院大学先導科学研究科助教］","subitem_description_type":"Other"}]},"item_2_relation_11":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN（科学研究費補助金データーベース）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-22570073/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"生物学"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"基盤研究(C)"}]},"item_2_text_21":{"attribute_name":"科研費の分科・細目","attribute_value_mlt":[{"subitem_text_value":"基礎生物学"}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2013"}]},"item_2_version_type_12":{"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":"松下, 敦子"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-08"}],"displaytype":"simple","filename":"22570073seika_matsushita.pdf","filesize":[{"value":"218.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"研究成果報告書","url":"https://ir.soken.ac.jp/record/5641/files/22570073seika_matsushita.pdf"},"version_id":"f6e43d4f-5507-480c-a59e-c86c34bd4a52"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"弱電気魚","subitem_subject_scheme":"Other"},{"subitem_subject":"神経伝達物質","subitem_subject_scheme":"Other"},{"subitem_subject":"時間情報","subitem_subject_scheme":"Other"},{"subitem_subject":"抑制性シナプス","subitem_subject_scheme":"Other"},{"subitem_subject":"聴覚系","subitem_subject_scheme":"Other"},{"subitem_subject":"時間感覚","subitem_subject_scheme":"Other"},{"subitem_subject":"免疫組織化学","subitem_subject_scheme":"Other"},{"subitem_subject":"比較神経解剖学","subitem_subject_scheme":"Other"},{"subitem_subject":"国際研究者交流 米国バージニア","subitem_subject_scheme":"Other"},{"subitem_subject":"神経会達物質","subitem_subject_scheme":"Other"},{"subitem_subject":"Calyx of Held","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":"超微小時間情報処理回路のシナプス伝達様式","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超微小時間情報処理回路のシナプス伝達様式"},{"subitem_title":"Neuroanatomical properties of 'time comparison circuit' in weakly electric fishes","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-08"},"publish_date":"2017-12-08","publish_status":"0","recid":"5641","relation_version_is_last":true,"title":["超微小時間情報処理回路のシナプス伝達様式"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:56:03.867359+00:00"}
