Brit.

/ˌpalɪə(ʊ)ˈθaləməs/,

/ˌpeɪlɪə(ʊ)ˈθaləməs/, U.S.

/ˈˌpeɪlioʊˈθæləməs/

Forms: see palaeo- comb. form and thalamus n.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: palaeo- comb. form, thalamus n.

Etymology: < palaeo- comb. form + thalamus n., after German Palaeothalamus (L. Edinger Vorlesungen über den Bau der nervösen Zentralorgane des Menschen u. der Tiere (ed. 8, 1911) I. 348). Compare earlier neothalamus n.

Anatomy and Zoology.
