1913Brain XXXVI. 159 In analogy with the archi⁓striatal commissure which connects the nuclei amygdalæ, and a possible commissure between the palæostriata in Meynert's commissure, such a connexion of the phylogenetically most recent parts of the striatum would not be improbable. 1921Tilney & Riley Form & Functions Cent. Nervous Syst. xliv. 805 In its process of evolution from the lower vertebrates to mammals, the primordial portion of the striate body corresponds to the globus pallidus. This structure may, therefore, be tentatively distinguished as the paleostriatum. Ibid. xlv. 819 This is known as the syndrome of the globus pallidus, juvenile paralysis agitans or the paleo-striatal syndrome of Ramsay Hunt. 1929[see neostriatum]. 1936C. U. A. Kappers et al. Compar. Anat. Nervous Syst. Vertebr. II. ix. 1369 The paleostriatal and neostriatal areas of birds and their reptilean equivalents are basal in origin. 1972[see neostriatum]. |
