Abstract
The science of hodology, from the Greek hodos, meaning road or path, has two principal aims, (a) the determination of the origin(s), course and site(s) of termination of fibre pathways, and (b) the study of the structure and composition of these pathways. During the past 150 years, an enormous body of data has been accumulated on the fibre pathways in the central nervous system of many vertebrate species, but a general hodology has not been developed. The present chapter will attempt to fill this gap. A brief overview of the evolutionary development of fibre compartments (Sect. 3.2) will be followed by some notes on the structure and the synaptic contacts of individual fibres (Sect. 3.3). Then, the origin, course and termination of fibre pathways (Sect. 3.4) and their structure and composition (Sect. 3.5) will be discussed. The final sections will present an outline of the three subdisciplines of hodology (Sect. 3.6) and some functional notes (Sect. 3.7). It should be emphasised that the drawings and photomicrographs in this chapter not only illustrate the text, but are central to its message.
