We used two-photon microscopy to measure the diameter of single penetrating arteries at different depths (~800 μm, layers I to V) of the frontal cortex, and examined changes in the diameter during focal electrical stimulation of the NBM (0.5 ms at 30 to 50 μA and 50 Hz) and hypercapnia (3% CO2 inhalation). Stimulation of the NBM caused diameter of penetrating arteries to increase by 9% to 13% of the prestimulus diameter throughout the different layers of the cortex, except at the cortical surface and upper part of layer V, where the diameter of penetrating arteries increased only slightly during NBM stimulation. Hypercapnia caused obvious dilation of the penetrating arteries in all cortical layers, including the surface arteries. The diameters began to increase within 1 second after the onset of NBM stimulation in the upper cortical layers, and later in lower layers. Our results indicate that activation of the NBM dilates cortical penetrating arteries in a layer-specific manner in magnitude and latency, presumably related to the density of cholinergic nerve terminals from the NBM","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/jcbfm.2013.92","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0271-678X","subitem_source_identifier_type":"ISSN"}]},"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":"Hotta, Harumi"}],"nameIdentifiers":[{"nameIdentifier":"465132","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masamoto, Kazuto"}],"nameIdentifiers":[{"nameIdentifier":"465133","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Sae"}],"nameIdentifiers":[{"nameIdentifier":"465134","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sekiguchi, Yuta"}],"nameIdentifiers":[{"nameIdentifier":"465135","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takuwa, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"465136","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawaguchi, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"465137","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sudo, Ryo"}],"nameIdentifiers":[{"nameIdentifier":"465138","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanishita, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"465139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"465140","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanno, Iwao"}],"nameIdentifiers":[{"nameIdentifier":"465141","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"465142","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"堀田 晴美","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"正本 和人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 さえ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465145","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関口 優太","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田桑 弘之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川口 拓之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤 浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅野 巖","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465150","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Layer-specific dilation of penetrating arteries induced by stimulation of the nucleus basalis of Meynert in the mouse frontal cortex","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Layer-specific dilation of penetrating arteries induced by stimulation of the nucleus basalis of Meynert in the mouse frontal cortex"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-12-04"},"publish_date":"2013-12-04","publish_status":"0","recid":"46658","relation_version_is_last":true,"title":["Layer-specific dilation of penetrating arteries induced by stimulation of the nucleus basalis of Meynert in the mouse frontal cortex"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:49:09.450267+00:00"}
