epithalamus

homology notes

The epithalamus has been historically conceived as a distinct neuroanatomical moiety within the diencephalon of all vertebrates. (...) The evolutionary origins of epithalamic structures are uncertain but asymmetry in this region is likely to have existed at the origin of the vertebrate, perhaps even the chordate, lineage.[well established][VHOG]
