paleothalamus

An obsolete term for what was regarded as the phylogentically oldest component of the thalamus (the midline nuclei). Because reciprocal connections are now known to exist between the former paleothalamus and the former neothalamus (the dorso- and ventrolateral nuclei), both terms have fallen into disfavour.
