Abstract

The vertebrate brain is remarkably prolific in displaying a distinct conservative bauplan that consists of a limited number of major brain parts and functional systems shared by all extant vertebrate species. This chapter describes the basic bauplan of the vertebrate brain, focuses on the comparative neural architecture of the forebrain in major vertebrate taxa, in particular of the telencephalon, reviews functional neuroanatomy, sensory inputs, and premotor/motor outputs, and discusses basal ganglia organization. Neuromeres are true transverse units of the central nervous system in the sense that they contain all dorsoventral parts of the neural tube at their anteroposterior axial location. The outlined neuromeric model is of great heuristic value for a comparative discussion of the brains of vertebrates, which include jawless (agnathan) lampreys and jawed (gnathostome) vertebrates. Despite great morphological differences between adult craniate brains, the comparative phyletic method allows to recognize those characters which define its ancestral condition.
