Central Nervous System of Vertebrates [PDF ebook] 

This comprehensive reference is clearly destined to become the definitive anatomical basis for all neuroscience research. The book provides a complete overview and comparison of the structural organization of all vertebrate groups, ranging from amphioxus and lamprey through fishes, amphibians and birds to mammals. The large specialised section of the work, devoted to the CNS of the various vertebrate groups, is preceded by introductory chapters on neurons, cell masses, fibre tracts, morphogenesis, methodology, and techniques. Although focusing on structure, the authors provide functional correlations throughout. This monumental work is, and will remain, unique; the only source of such brilliant illustrations at both the macroscopic and microscopic levels.
