Chondrichthyes display a wide range of  cerebralization, with the highest brain weight\/body  weight ratio represented by galeomorph sharks and  batoids of the myliobatiform order. The examination  was extended to representatives of all these  important groups and the book presents the first  study on the glial architecture of a Holocephali as  well. The present work supplements the former glial  impregnation studies; three different astroglial  markers - glial fibrillary acidic protein, S-100  protein, and glutamine synthetase - were  investigated by immunohistochemical methods,  applying both diaminobenzidine and fluorescent  techniques. To reveal characteristic features  of the blood-brain barrier of cartilaginous fishes  the dystroglycan complex and some of its associated  proteins were also investigated, as well as  aquaporins. The book also highlights evolutionary  changes of astroglia in chondrichthyes and discusses  the significance of the enlarged brain parts in  ecological perspectives.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838316109\"\u003e\u003ch3\u003eCerebralization, Astroglial Architecture and Blood-Brain Barrier Composition\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838316109","offer_id":39497036005469,"sku":"9783838316109","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/bc7c0158-833d-4db5-997c-34fc889da11b.jpg?v=1749619212","url":"https:\/\/shop.autorenwelt.de\/products\/on-the-brain-of-cartilaginous-fishes-von-ph-d-ari","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
