Long-survival [3H]thymidine autoradiography was used to quantitatively determine the time of origin of neurons in the endopiriform nucleus and the claustrum in rats killed on postnatal day 60 after their dams received two consecutive daily injections of [3H]thymidine on embryonic day E13 and E14, E14 and E15, ... E21 and E22. The claustrum originates late, on E15 and E16, and has a strong gradient in the longitudinal direction, posterior (older) to anterior (younger). In contrast, the… 
Neuroepithelial origin of the insular and endopiriform parts of the claustrum
TLDR
It is suggested that although the endopiriform claustrum originates from the ventral pallium, the insular claustrums originated from both the lateral and the ventrals pallial portions.
Cell migration from the corticostriatal angle to the basal telencephalon in rat embryos
TLDR
Data indicated that the majority of neurons in the dense cell layer of the olfactory tubercle reached this point through the LCS, and one of the origins of the cells in the LCS would be in the corticostriatal angle.
NPY-, SOM- and VIP-containing interneurons in postnatal development of the rat claustrum
TLDR
The results indicate that neuropeptide-containing interneurons are not morphologically mature at the moment of birth, and the characteristic features of neuronal bodies and the relatively long period of postnatal development may indicate their migration from the subcortical neurogenetic centers.
Development and early postnatal maturation of the primary olfactory cortex.
TLDR
Tritiated thymidine autoradiography was used to study the origin and distribution of neurons in the primary olfactory cortex of the rat, finding labelled cells in layer I were found flanking the lateral Olfactory tract, but rarely in the adult suggesting that they disappear or transform postnatally.
Dynamics of Cell Migration from the Lateral Ganglionic Eminence in the Rat
TLDR
It is concluded that cells of the primary olfactory cortex derive from the lateral ganglionic eminence and that some early generated cells migrating from the longitudinal eminence transgress the cortico-striatal boundary entering the preplate of the neocortical primordium.
Developmental gene expression in the mouse clarifies the organization of the claustrum and related endopiriform nuclei
TLDR
The ventral endopiriform nucleus is formed by radially migrating Nr4a2‐negative cells in the ventral pallium; it is therefore developmentally distinct from the Nr2‐postive dorsal endopIRiform nucleus, which is a lateral pallial derivative.
The “Neostriatum” Develops as Part of the Lateral Pallium in Birds
TLDR
A comparative analysis suggests that the avian neostriatum develops from a precursor region that in other vertebrates gives rise to olfactory cortex and, when present, to other components of the piriform lobe, such as the endopiriform claustrum and basolateral amygdala.

TLDR
It is proposed here that, as the degree of development of structures that form the deeper tier of the pallium varies across the stages of embryology and across phylogeny, mutations may have occurred during evolution at the origin of mammals that had profound consequences for the fate of neural populations generated in the region of the CS and its neighboring pallial germinal zone.
Developmental Patterning and Neurogenetic Gradients of Nurr1 Positive Neurons in the Rat Claustrum and Lateral Cortex
TLDR
The findings suggest that claustrum and Nurr1 positive neurons in the lateral cortex are born sequentially over several days of embryonic development and contribute toward charting the complex developmental pattern of the claustrums in rodents.
The Claustrum Is Not Missing from All Monotreme Brains
TLDR
It is found that although the claustrum is a small structure in the echidna brain, it is nevertheless clearly present as loosely clustered neurons embedded in the white matter ventrolateral to the putamen and deep to the piriform and entorhinal cortices.

Development of layer I and the subplate in the rat neocortex
TLDR
Development of layer I and the subplate of the rat neocortex was examined with [3H]thymidine autoradiography and small- to medium-sized horizontal cells in layer I have an extensive period of neurogenesis with an "outside-in" gradient.

TLDR
Evidence is presented that neurogenetic gradients in the magnocellular basal telencephalic neurons can be correlated with their anatomical projections to the cerebral cortex.

TLDR
To study morphogenesis, pregnant females were given single injections of [3H]thymidine during gestation and embryos were removed in successive 24-h intervals (sequential-survival).
Cell migration in the rat embryonic neocortex
TLDR
Three‐dimensional reconstructions of the normal rat embryonic (E) neocortex using Skandha and [3H]thymidine autoradiography show that the neocortical ventricular zone shrinks rapidly in the medial direction during cortical morphogenesis, and that cells generated in the neocortex migrate in the lateral cortical stream for 5 or more days and accumulate in a reservoir.
The organization of the ipsi- and contralateral claustrocortical system in rat with notes on the bilateral claustrocortical projections in cat
TLDR
The intricate organization of the claustral-ascending projections suggests that the nucleus is involved in different cortical activities and that its efferents may also provide the substrate of a powerful subcortical mechanism of interhemispheric communication.

TLDR
The cat's dorsocaudal claustrum was studied in Golgi preparations, by electron microscopy, and by anterograde and retrograde tracer techniques, finding the claustrocortical axons terminate in all cortical layers but most heavily in layers IV and VI.

The pattern of connections between the claustrum and visual cortex in the rat differs fundamentally with that found in other species.

TLDR
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.

The connections of the medium and large size cells of the islands of Calleja Complex were studied in the albino rat with anterograde and retrograde transport of horseradish peroxidase (HRP) and fluorescent tracers and are consistent with the concept that the ICC is a striato-pallidal structure.
