We studied (1) the neuronal connections in the lamina and (2) the\npossible spectral oppoency in the photoreceptors and lamina monopolar cells (LMCs).\nWe analyzed serial EM pictures of the lamina and revealed all synaptic connections in six lamina\ncartridges including both intra- and inter-cartridge connections. This provides the second data set\nof such following the one in Drosophila melanogaster. We also analyzed the possible spectral\nopponencies in the lamina, and found two histamine-gated chloride channels appeared to be involved\nin the photoreceptor spectral opponency.","subitem_description_type":"Abstract"}]},"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/grant/KAKENHI-PROJECT-26251036/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"神経行動学"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"基盤研究（A）（一般）"}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2017"}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蟻川, 謙太郎"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-07"}],"displaytype":"simple","filename":"26251036seika.pdf","filesize":[{"value":"394.6 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/6122/files/26251036seika.pdf"},"version_id":"332f8e39-b91a-417b-a8c8-8e611e5b5ee1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"昆虫","subitem_subject_scheme":"Other"},{"subitem_subject":"色覚","subitem_subject_scheme":"Other"},{"subitem_subject":"視葉板","subitem_subject_scheme":"Other"},{"subitem_subject":"波長対比性","subitem_subject_scheme":"Other"},{"subitem_subject":"コネクトーム","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":"昆虫視葉板における色覚初期過程の解剖学的・生理学的解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"昆虫視葉板における色覚初期過程の解剖学的・生理学的解析"},{"subitem_title":"Anatomical and physiological analysis of early color processing in the insect lamina　　","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-07"},"publish_date":"2020-07-07","publish_status":"0","recid":"6122","relation_version_is_last":true,"title":["昆虫視葉板における色覚初期過程の解剖学的・生理学的解析"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:14:19.110836+00:00"}
