palæoˈpallium Anat.
Also (chiefly U.S.) paleo-, and with hyphen.
[mod.L., f. palæo-, paleo- b + pallium 3 d.]
A phylogenetically older portion of the pallium of the brain, which comprises mainly the pyriform lobe (the hippocampal formation or archipallium is sometimes included).
1909C. V. A. Kappers in Arch. Neurol. & Psychiatry IV. 161 This nervous substance, in order to distinguish it from the subventricular grey substance, should be called palæo-pallium. 1933[see archipallium]. 1948A. Brodal Neurol. Anat. x. 324 (caption) In amphibians..a dorsal area is found between the hippocampal area (archi⁓pallium) and the piriform area (palæo-pallium). 1962E. C. Crosby et al. Correl. Anat. Nerv. Syst. vii. 411/1 ‘Paleopallium’ is a term applied to the pyriform cortex; that is, to portions at least of the hippocampal gyrus. 1972T. W. Jenkins Functional Mammalian Neuroanat. ii. 35/1 Based on the phylogenetic age, the olfactory cortex at the base of the brain, which is the older cortex is referred to as the archipallium (archicortex), or paleo⁓pallium (paleocortex).
Hence palæoˈpallial a., of or pertaining to the palæopallium.
1936C. U. A. Kappers et al. Compar. Anat. Nerv. Syst. Vertebr. II. ix. 1482 In mammals the discharge paths between the archipallial, paleopallial, and archistriatal regions and the diencephalic centers are essentially those which have been described for lower forms. 1962E. C. Crosby et al. Correl. Anat. Nerv. Syst. vii. 411 The non⁓olfactory functions of paleopallial and archipallial areas may become dominant in higher mammals. |
