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", "download_preview_message": "", "file_order": 0, "filename": "2873.full.pdf", "filesize": [{"value": "234.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 234600.0, "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"], "permalink_uri": "https://ir.soken.ac.jp/records/3327", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-01-18"}, "publish_date": "2013-01-18", "publish_status": "0", "recid": "3327", "relation": {}, "relation_version_is_last": true, "title": ["Color discrimination at the spatial resolution limit in a swallowtail butterfly, Papilio xuthus"], "weko_shared_id": 21}
