We trained 4 rhesus monkeys in a task where a visually- triggered bar-release was required in every trial. A visual cue presented at the beginning of each trial indicated one of two rewarding conditions: a reward would be either immediately delivered or postponed (7s) after the correct bar release. When each member of a categorical cue set was associated with a rewarding condition (e.g.  \ndog = immediate; cat = postponed), the monkeys discriminated the categories with different error rates (p<0.001, X2-test) even on the first day. After bilateral removal of LPFC, the monkeys still showed different error rates between categories with both learned (e.g. dogs/cats) and novel categories (e.g. cars/trucks). Furthermore, the monkeys generalized the association to trial-unique cue sets with different error rates. These results indicate that LPFC is not essential for learning of visual categories and generalization to novel stimuli.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Ｎｅｕｒｏｓｃｉｅｎｃｅ　2008","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Minamimoto, Takafumi"}],"nameIdentifiers":[{"nameIdentifier":"681369","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"681370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"南本 敬史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681371","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Rapid learning of visual categories without lateral prefrontal cortex in monkeys","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rapid learning of visual categories without lateral prefrontal cortex in monkeys"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-08-14"},"publish_date":"2008-08-14","publish_status":"0","recid":"69429","relation_version_is_last":true,"title":["Rapid learning of visual categories without lateral prefrontal cortex in monkeys"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:14:35.474794+00:00"}
