The cerebral cortex, particularly that half typically targeted "neocortex," is likely one of the hallmarks of mammalian evolution and reaches its maximum measurement, quite conversing, and its widest structural range within the human mind. The evolution of this constitution, as impressive for the massive numbers of neurons that it comprises as for the variety of behaviors that it controls, has been of abiding curiosity to many generations of neuroscientists. but few theories of cortical evo­ lution were proposed and none has stood the try of time. specifically, no conception has been winning in bridging the evolutionary hole that looks to exist among the pallium of nonmammalian vertebrates and the neocortex of mam­ mals. unquestionably this stems largely from the fast divergence of non­ mammalian and mammalian kinds and the inability of latest species whose telencephalic wall may be noticeable as having transitional features. The mono­ treme cortex, for instance, is surely mammalian in association and that of no residing reptile comes as regards to akin to it. but anatomists similar to Ramon y Cajal, on studying the finer information of cortical constitution, have been struck by way of the similarities in neuronal shape, really of the pyramidal cells, and their predisposition to laminar alignment shared via representatives of all vertebrate classes.

10). In 19 THE TELENCEPHAWN OF CARTILAGINOUS FISHES 20 CHAPTER I holocephalian fishes, the large intraventricular protrusion of the lateral telencephalic wall (Figs. 13, 14) has been considered as striatal swellings (Ariens Kappers and Carpenter, 1911; Holmgren, 1922; Faucette, 1969a,b). , area subpallialis 6, 7, and 8 (Fig. 19), and it is still uncertain whether any of these three cell masses can be compared with the shark's striatum. The septal region comprises the medial as well as the ventromedial portion of the subpallium in both sharks studied.

Introductory Notes The structure of the telencephalon of actinopterygian fishes has been studied by a large number of observers, among whom may be mentioned Johnston (1911), Sheldon (1912), Holmgren (1920), Ariens Kappers et ai. (1936), Weston (1937), Meader (1939), Nieuwenhuys (1962a,b, 1963, 1966, 1983), Northcutt and Braford (1980), Bass (1981a,b,c), Ito et ai. (1982), Murakami et ai. (1983), Northcutt and Davis (1983), and Levine and Dethier (1985). These studies have yielded numerous different terminologies, many of which reflect the views of the pertinent authors on the question as to how the various parts of the actinopterygian forebrain should be interpreted.

1, 2). This part of the evagination process has been described by Holmgren (1922) and others as the bending inward or inversion of the pallium. The thin-walled telencephalon of lungfishes, which will be discussed in the next chapter, has much in common with that of amphibians. In this group the evagination takes place particularly in a rostral and ventral direction; a caudal evagination is practically absent, however. In amniotes the evagination process is complicated by the formation of one or two ventrolaterally situated thickenings which are going to protrude into the ventricular cavity (Fig.
