Etymology

borrowed from New Latin (in a German context), from hypo- hypo- + thalamus thalamus

Note: The term was introduced in an article by the Swiss-born anatomist Wilhelm His (1831-1904), "Ueber das frontale Ende des Gehirnrohres," Archiv für Anatomie und Physiologie: Anatomische Abtheilung, Jahrgang 1893, p. 159. His attributes the suggestion of the word to his colleague "Waldeyer" (the anatomist Heinrich Wilhelm Gottfried von Waldeyer-Hartz, 1836-1921), as a replacement for his own coinage Regio subthalamica.
