One potential mechanism underpinning this relationship is via modulation of cerebrovascular parameters and therefore increasingly, neuroimaging techniques such as near-infrared spectroscopy (NIRS) and fMRI have been applied to investigate the effect of n-3 PUFAs on cerebral blood flow in humans. These studies have revealed that n-3 PUFA supplementation has subtle effects on cerebral blood flow which may indeed underpin the positive relationship between their intake and cognition across the lifespan; at present these changes are more apparent in children and younger adults.","PeriodicalId":18083,"journal":{"name":"Lipid Technology","volume":"28 12","pages":"197-199"},"PeriodicalIF":0.0,"publicationDate":"2016-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/lite.201600052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79400687","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}
