In biology terms the difference between homology and hodology
is that homology is a correspondence of structures in two life forms with a common evolutionary origin, such as flippers and hands while hodology is in brain physiology, it is the study of the interconnections of brain cells.
As nouns the difference between homology and hodology
is that homology is a homologous relationship while hodology is the study of pathways.

* (mathematics) When used attributively before the name of a topological space, as in "homology n -sphere" or "homology manifold", the reference is to a space whose homology is the same as that of the space mentioned: an homology manifold, for example, is a space whose homology is that of some manifold.
