The cytogenesis and morphogenesis of the rat hippocampus was examined with the techniques of 3H‐thymidine autoradiography, cell pyknosis produced by low‐level X‐irradiation, and quantitative histology. 

Prenatal development of the cerebellar system in the rat. I. Cytogenesis and histogenesis of the deep nuclei and the cortex of the cerebellum

To quantify the time of origin of different classes of cerebellar neurons with the progressively delayed labelling procedure, autoradiograms from adult rats whose mothers were injected with two successive daily doses of 3H‐thymidine on overlapping days from day E13 on were used.

Neurogenesis in the rat amygdala was examined with 3H‐thymidine radiography and the percentage of labelled cells and the proportion of cells added during each day of formation were determined at several anatomical levels within the following components of the amygdala.

Neurogenesis in the rat septal region was examined with3H‐thymidine autoradiography and the oldest neurons are located ventrally while progressively younger cells are found dorsally beneath the inferior horn of the lateral ventricle.

Histological and Morphological Analysis of the Hippocampal Subfields in the Adult Rat

This study confirmed the existence of differences in nerve fiber distribution among the subfields of the hippocampus which is attributed to differences in the embryonic development processes and to the selectivity of the different connections.

Morphogenesis of the entire hippocampal region was examined in normal rats from embryonic (E) day E10 to E22 and on postnatal (P) days P1, P7, and P21, and was correlated with autoradiographic

Mosaic organization of the hippocampal neuroepithelium and the multiple germinal sources of dentate granule cells

The results indicate that the hippocampal neuroepithelium consists of three morphogenetically discrete components—the Ammonic neuroepIthelium, the primary dentate neuroepIThelium and the fimbrial glioepit Helium—and that these are discrete sources of the large neurons of Ammon's horn, the smaller granular neurons of the dentate gyrus, and the glial cells of thefimbria.

Electro microscopic observations reported in this study reveal that a steady rate of granule cell neurogenesis occurs during the first year of a rodent's life, and that newly formed granule neurons in the dentate gyrus of the newborn mouse and adult rat are a result of neuroblast division.

Developmental changes in GABA neurons of the rat dentate gyrus: An in situ hybridization and birthdating study

The changes in the mRNA and birthdating patterns suggest that some of the early‐appearing GABA neurons within the developing molecular layer of the dentate gyrus may alter their positions to eventually become the mature GABA population along the inner border of the granule cell layer.

Autoradiographic and histological studies of postnatal neurogenesis. I. A longitudinal investigation of the kinetics, migration and transformation of cells incoorporating tritiated thymidine in neonate rats, with special reference to postnatal neurogenesis in some brain regions

It was established that cells multiplying in the ependymal and subependymal walls of the Olfactory ventricle migrate outward into the olfactory bulb, where they become differentiated into granule cells, and, to a lesser extent, other types of nerve cells of the cerebellar cortex.

Autoradiographic and histological studies of post-natal neurogenesis IV

The results established that the major target structure of cell production in the subependymal layer of the lateral ventricle in young-adult rats is the olfactory bulb, with only moderate contribution made to the anterior neocortex and basal ganglia.

Irradiation of the infant rat hippocampus using a schedule derived from previous cerebellar autoradiographic and irradiation studies should reduce the population of granule cells without directly harming the prenatally-formed pyramidal cells of Amnion's horn.

Autoradiographic investigation of cell proliferation in the brains of rats and cats

The results indicate that glia cells can multiply in the brains of young adult rats and adult cats and they support the possibility that new neurons may be formed in forebrain structures, both in rodents and carnivores.

The skulls of 9-day old rats were irradiated with 100 R x-ray and they were allowed to survive for varying intervals, ranging from 10 minutes to 24 hours, and several phases of imminent cell death were distinguished.

Autoradiographic and histological evidence of postnatal hippocampal neurogenesis in rats

It is postulated that undifferentiated cells migrate postnatally from the forebrain ventricles to the hippocampus where they become differentiated, implicating that they may function as receptors of gonadal hormones.
