We investigated cortical responses elicited at the offset of tonal stimuli using flavoprotein fluorescence imaging in mice. Off-responses were clearly observed at the offset of tonal stimuli lasting for 7 s, but not after stimuli lasting for 1 s. Off-responses to the short stimuli appeared in a similar cortical region, when conditioning tonal stimuli lasting for 5–20 s preceded the stimuli. MK-801, an inhibitor of NMDA receptors, suppressed the two types of off-responses, suggesting that disinhibition produced by NMDA receptor-dependent synaptic depression might be involved in the off-responses. The peak off-responses were localized in a small region adjacent to the primary auditory cortex, and no frequency-dependent shift of the response peaks was found. Frequency matching of preceding tonal stimuli with short test stimuli was not required for inducing off-responses to short stimuli. Two-photon calcium imaging demonstrated significantly larger neuronal off-responses to stimuli lasting for 7 s in this field, compared with off-responses to stimuli lasting for 1 s. The present results indicate the presence of an auditory cortical field responding to long-lasting tonal offsets, possibly for temporal information processing.", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "学位の種類: 博士（医学）. 報告番号: 甲第4267号. 学位記番号: 新大院博（医）甲第745号. 学位授与年月日: 平成29年3月23日", "subitem_description_type": "Other"}, {"subitem_description": "Scientific Reports 6, Article number: 34421 (2016)", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博（医）甲第745号", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "13101甲第4267号"}]}, "item_6_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "50990", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "馬場, 洋徳"}]}]}, "item_6_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学"}]}, "item_6_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1038/srep34421", "subitem_relation_type_select": "DOI"}}]}, "item_6_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "ETD"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Baba, Hironori"}], "nameIdentifiers": [{"nameIdentifier": "50989", "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": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "h28nmk745.pdf", "filesize": [{"value": "2.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2200000.0, "url": {"label": "本文", "url": "https://niigata-u.repo.nii.ac.jp/record/5855/files/h28nmk745.pdf"}, "version_id": "6138d254-c2d3-423b-ac47-4c7495944a56"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "h28nmk745_a.pdf", "filesize": [{"value": "198.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 198500.0, "url": {"label": "要旨", "url": "https://niigata-u.repo.nii.ac.jp/record/5855/files/h28nmk745_a.pdf"}, "version_id": "793e8194-1741-4a48-9e5c-cb6e64ff2b53"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Auditory cortical field coding long-lasting tonal offsets in mice.", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Auditory cortical field coding long-lasting tonal offsets in mice."}, {"subitem_title": "Auditory cortical field coding long-lasting tonal offsets in mice.", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "562"], "permalink_uri": "http://hdl.handle.net/10191/47612", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-09-11"}, "publish_date": "2018-09-11", "publish_status": "0", "recid": "5855", "relation": {}, "relation_version_is_last": true, "title": ["Auditory cortical field coding long-lasting tonal offsets in mice."], "weko_shared_id": 2}
