Anatomically, the pixels correspond to single cone outer segments in humans and to single rhabdoms in insects. Although an outer segment and a rhabdom are equivalent organelles containing visual pigment molecules, they are strikingly different in spectral terms. The cone outer segment is the photoreceptor cell part that expresses a single type of visual pigment, and is therefore monochromatic. On the other hand, a rhabdom is composed of several photoreceptor cells with different spectral sensitivities and is therefore polychromatic. The polychromatic organization of the rhabdom suggests that insects can resolve wavelength information in a single pixel, which is an ability that humans do not have. We first trained the Japanese yellow swallowtail butterfly Papilio xuthus to feed on sucrose solution at a paper disk of certain color. We then let the trained butterflies discriminate disks of the training color and grey disks each presented in a Y-maze apparatus. Papilio correctly selected the colored disk when the visual angle was greater than 1.18° for blue, 1.53° for green or 0.96° for red: they appeared to see colors in single pixels to some extent. This ability may compensate their rather low spatial resolution.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Company of Biologists Ltd"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1242/jeb.02311 "}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1242/jeb.02311 ","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Copyright"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.biologists.com/dmm/dmm_information.html#anchor_access","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Company of Biologists Limited 2006 "}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00220949 ","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":"TAKEUCHI, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"450","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ARIKAWA, Kentaro"}],"nameIdentifiers":[{"nameIdentifier":"821","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KINOSHITA, Michiyo"}],"nameIdentifiers":[{"nameIdentifier":"370","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-01-18"}],"displaytype":"simple","filename":"2873.full.pdf","filesize":[{"value":"234.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"2873.full","url":"https://ir.soken.ac.jp/record/3327/files/2873.full.pdf"},"version_id":"4966ab12-4705-476c-8710-b0af61b8b85f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Color discrimination at the spatial resolution limit in a swallowtail butterfly, Papilio xuthus","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Color discrimination at the spatial resolution limit in a swallowtail butterfly, Papilio xuthus"},{"subitem_title":"Color discrimination at the spatial resolution limit in a swallowtail butterfly, Papilio xuthus","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["96","119","267","286"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-18"},"publish_date":"2013-01-18","publish_status":"0","recid":"3327","relation_version_is_last":true,"title":["Color discrimination at the spatial resolution limit in a swallowtail butterfly, Papilio xuthus"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:11:31.666197+00:00"}
