We show that the degree of synchronization varies with the development of a stroke caused by severe stress, which is reflected in the reduced average duration of segments with frequency locking. Such changes differ between macro- and microcerebral dynamics and are more pronounced for a network of small vessels surrounding the sagittal sinus.","PeriodicalId":203512,"journal":{"name":"Saratov Fall Meeting 2019: Computations and Data Analysis: from Nanoscale Tools to Brain Functions","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
