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","filename":"h28nmk745.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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","filename":"h28nmk745_a.pdf","filesize":[{"value":"198.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-09-11"},"publish_date":"2018-09-11","publish_status":"0","recid":"5855","relation_version_is_last":true,"title":["Auditory cortical field coding long-lasting tonal offsets in mice."],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T03:39:05.798025+00:00"}
