Neocortex development during severe malnutrition in the rat
The American Journal of Clinical Nutrition, 1976Histological methods (Golgi-Cox and Nissl) were used to study the maturation of the large pyramidal cells of layer V of the occipital cortex in malnourished rats (according to the method of Araya et al.). The main alterations were observed in pyramidal cells of cortical alyer V; These showed a decrease of the number and span of dendritic basilar ...

An epigenetic circuit controls neurogenic programs during neocortex development
Development, 2021ABSTRACT The production and expansion of intermediate progenitors (IPs) are essential for neocortical neurogenesis during development and over evolution. Here, we have characterized an epigenetic circuit that precisely controls neurogenic programs, particularly properties of IPs, during neocortical development.

Tachykinin Expression and Localization in Developing Feline Neocortex
Developmental Neuroscience, 2003Developmental patterns of expression and localization of tachykinins in feline neocortex were determined by qualitative immunohistochemical means. Three observations were obtained. (1) By midgestation, tachykinins were progressively accumulated in an infrequent (<1%) population of interneurons (sparse dendritic spines) settled mainly in superficial ...

Cell cycle dependence of laminar determination in developing neocortex
Science, 1991The neocortex is patterned in layers of neurons that are generated in an orderly sequence during development. This correlation between cell birthday and laminar fate prompted an examination of how neuronal phenotypes are determined in the developing cortex. At various times after labeling with [3H]thymidine, embryonic progenitor cells were transplanted

Neurotrophins and activity-dependent development of the neocortex
Current Opinion in Neurobiology, 1996A number of recent results suggest that neurotrophins play an important role in early development as well as in the later, activity-dependent processes important for the final shaping of cortical connections. Many neurotrophins and their receptors are regulated in parallel with the 'critical period' in development, and their application to the ...

Allometry, evolution and development of neocortex size in mammals
2019Variation in neocortex size is one of the defining features of mammalian brain evolution. The paramount assumption has been that neocortex size indicates a monotonic allometric relationship with brain size. This assumption holds the concomitant neurodevelopmental assumption that the ontogenetic trajectory of neocortex size is so stable across species ...

Anatomy and Embryology, 1994
By way of introduction, an outline is presented of the origin and evolutionary development of the neocortex. A cortical formation is lacking in amphibians, but a simple three-layered cortex is present throughout the pallium of reptiles. In mammals, two three-layered cortical structures, i.e.
