“…Understanding the similarities and differences of the DVR not only gives insight into regional function in both of these classes, but it can also give clues as to why the DVR originally formed and how it will continue to develop. Warner's (1931;1946;1947) and Carey's (1967) investigations were the first studies of the snake telencephalon, and have served as the foundation leading to the advent of morphology and pathway studies begun by Ulinski and Halpern in the 1970s (Halpern, 1980;Ulinski, 1974;Ulinski, 1975;Ulinski, 1978). Reptiles are the first vertebrate class in which distinct cortical regions become obvious.…”

The development of the human amygdaloid complex is described beginning at the time that it first appears, when the cerebral hemispheres begin to evaginate (approximately 8-9 m m ) , and including a fetus of 27.4 mm CR length Both Nissl and protargol silver series, transversely and sagittally sectioned, were used.The earliest cell migration representing the striatal complex is from the germinal epithelium in the region of the interventricular foramen, lateral to the primordial hippocampal formation. This is the characteristic topographic location of the amygdala, which, therefore, 1s the first portion of the human striatal complex to appear embwologically. All of the amygdaloid nuclei identified develop by the migration of neuroblasts from the germinal epithelium.The three main subdivisions of the amygdaloid complex (anterior amygdaloid area, corticomedial complex and basolateral nuclear group) are identifiable almost immediately after the primordial amygdala appears (9.5 m m in the material studied). In this embryo the cortical and medial nuclei are identifiable, but the central nucleus was not seen until 22.2 mm and the nucleus of the lateral olfactory tract was not identified even in the oldest fetuses.The basolateral complex differentiates much later than the corticomedial complex and all of the nuclear components became identifiable at the same time (20.7 mni embryo). However the basal nucleus is best represented, the accessory basal next in size, and the lateral only just appearing. In the oldest fetus the subdivisions of the basal and accessory basal nuclei seen in the adult brain are recognizable. Even before the individual nuclei appear, the basolateral complex is much larger than the corticomedial complex. The lateral to medial rotation of the amygdaloid complex has not yet begun in the oldest Petuses, but the posterior end of the lateral ventricle is beginning to turn anteriorly.During early development, all cells of the amygdala are derived from the lateral striatal ridge, the only one present until 14.0 mm. At 20.7 m m and later neuroblasts are contributed from the medial striatal ridge also. Although the greater part of the basolateral amygdaloid complex is derived from the lateral ridge, some cells are contributed from the medial ridge, particularly to the accessory basal nucleus. By contrast, the corticomedial complex is derived in part from the medial striatal ridge, after it appears, even though the early development is from the lateral ridge.Comparisons between the amygdala at different developmental stages and the amygdala in fishes, in amphibians, in reptiles and in lower mammals are made. The topographic relationships between the amygdala and the hippocampal formation, the piriform cortex and the caudate, the putamen and the globus pallidus are considered.The archistriatum, or amygdala, and the paleostriatum, or globus pallidus, are commonly considered old parts of the striatal complex phylogenetically ( Ariens Kappers, Huber and Crosby, '36; Crosby, DeJonge and Schneider, '66).

The Chimaerae are phylogenetically old cartilagenous fish which are included in the class Chondrichthyes with the sharks and rays. The telencephalon of these fish is connected to the diencephalon by a unique fibrous stalk. The telencephalic heniispheres are united only ventrally at midhemisphere levels in the region of the hippocampal and anterior commissures. The lateral ventricles join the midline ventricle through the interventricular foramen at this level.Ea.ch olfactory bulb is divided into a dorsal and ventral part and each has a dorsal and a ventral accessory olfactory bulb. A dorsaI and a ventral olfactory nerve unite the respective parts of the bulb with a nasal sac. The cupshaped mitral cell laminae share a common granular cell layer where they are in apposition. The granular lamina is replaced caudally by the anterior olfactory nucleus.The medially situated primordial hippocampal formation consists of the anterior continuation, the primordial subiculum, the cornu ammonis and the dentate gyrus.Septa1 nuclei recognizable in this form include: a medial and a lateral septa1 nucleus, a septohippocampal nucleus, a nucleus triangularis, an accumbens nucleus, and a nucleus of the diagonal band. The medial zone of the olfactory tubercle occupies the ventromedial hemisphere wall. Major fiber connections of the medial limbic lobe include: the medial olfactory tract, the fornix, the medial forebrain bundle and the medial corticohabenular tract.
