The only AchE-positive structures found were neuronal cell bodies and processes, morphologically classified as stellate and fusiform neurons of large, medium and small size. Large ones prevailed in the dorsal zone. The neurons were homogeneously distributed in the rostral area of the SFO. The penetration and ramification of large blood vessels produced a decreasing neuronal density in the medium-caudal area. The architecture of the SFO in sagittal sections comprised a central zone with neurons juxtaposed to the walls of the vascular plexus, whose dendritic and axonal processes showed an intricate pattern without a special arrangement. This neuronal zone of the SFO was surrounded by a peripheral layer of neurons with axonal projections to the rostral area. This layer was thicker in the dorsal zone of the SFO, where axonal fibers \"climbing-up\" from the central perivascular neurons could be demonstrated. In coronal sections some neurons with prolongations of arcuate distribution connected the dorsal and ventral zones.</p>","PeriodicalId":75534,"journal":{"name":"Archives d'anatomie, d'histologie et d'embryologie normales et experimentales","volume":"74 ","pages":"65-76"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12539497","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}
