neopallium Anat.|niːəʊˈpælɪəm|
Also (with hyphen) neo-pallium. Pl. -pallia.
[mod.L., f. neo- 1 e + pallium.]
The phylogenetically youngest portion of the pallium of the brain, which appears first among the more advanced reptiles and which among the mammals has become the largest part of the brain. Cf. neocortex.
1901G. E. Smith in Jrnl. Anat. & Physiol. XXXV. 431 It is only one of the three histological formations which constitute the true pallium; and, as it is the latest of these to reach the height of its development, we may call it the ‘new pallium’ or..‘neopallium’, in contradistinction to the ‘old pallium’ of the Sauropsida and earlier Vertebrata, which is chiefly formed of the other two pallial areas. 1907Arch. Neurol. III. 51 Maps have been obtained of these neopallia which are fairly full. Ibid. 52 The term neopallium is employed throughout in the sense suggested by Elliot Smith to indicate the variable area intercalated between the ‘basal pallium’ or pyriform lobe and the marginal pallium, or hippocampus. 1922Glasgow Herald 23 Dec. 4/2 When our ancestors, with their free hands, their enlarged cerebral cortex or neopallium, and their capacity for co-operative action, had resources sufficient to enable them to stand up to Carnivores.., they left the trees and became once more terrestrial. 1948A. Brodal Neurol. Anat. x. 323 With the development of the neopallium or neo-cortex, the two more primitive areas are finally pushed medially, and in man are found entirely on the medial aspect of the hemisphere. 1973Gray's Anat. (ed. 35) vii. 921/1 In the course of evolution visual, auditory and other conduction paths have been transferred, through the thalamus, to the pallium of the cerebral hemispheres... Consequently, each cerebral hemisphere enlarges as a result of the formation of an additional region, the neopallium.
Hence neoˈpallial a., of or pertaining to the neopallium.
1907Arch. Neurol. III. 112 This appears to be the lowest grade of conscious neopallial association—i.e., of psychic function. 1921Tilney & Riley Form & Functions Central Nervous Syst. xlii. 772 (heading) Neopallial projection system. 1953G. A. G. Mitchell Anat. Autonomic Nerv. Syst. v. 66 This neopallial responsibility for autonomic activities is shared by subcortical centres in the hypothalamus. 1962E. C. Crosby et al. Correl. Anat. Nerv. Syst. vii. 411/1 Neopallial cortex makes up the major portion of the cerebral cortex in man. |
