Coordinated scaling of cortical and cerebellar numbers of neurons. [PDF]

Front Neuroanat, 2010
While larger brains possess concertedly larger cerebral cortices and cerebella, the relative size of the cerebral cortex increases with brain size, but relative cerebellar size does not.

Densities and numbers of calbindin and parvalbumin positive neurons across the rat and mouse brain

iScience, 2021
Summary: The calcium-binding proteins parvalbumin and calbindin are expressed in neuronal populations regulating brain networks involved in spatial navigation, memory processes, and social interactions.

Widespread Doublecortin Expression in the Cerebral Cortex of the Octodon degus

Frontiers in Neuroanatomy, 2021
It has been demonstrated that in adulthood rodents show newly born neurons in the subgranular layer (SGL) of the dentate gyrus (DG), and in the subventricular zone (SVZ). The neurons generated in the SVZ migrate through the rostral migratory stream (RMS)

Passage number affects differentiation of sensory neurons from human induced pluripotent stem cells

Scientific Reports, 2022
Induced pluripotent stem cells (iPSCs) are a valuable resource for neurological disease-modeling and drug discovery due to their ability to differentiate into neurons reflecting the genetics of the patient from which they are derived.

Cellular scaling rules for the brain of Artiodactyla include a highly folded cortex with few neurons

Frontiers in Neuroanatomy, 2014
Quantitative analysis of the cellular composition of rodent, primate, insectivore and afrotherian brains has shown that nonneuronal scaling rules are similar across these mammalian orders that diverged about 95 million years ago, and therefore appear to ...

Distribution of neurons in functional areas of the mouse cerebral cortex reveals quantitatively different cortical zones

Frontiers in Neuroanatomy, 2013
How are neurons distributed along the cortical surface and across functional areas? Here we use the isotropic fractionator (Herculano-Houzel and Lent, 2005) to analyze the distribution of neurons across the entire isocortex of the mouse, divided into 18 ...

Greater addition of neurons to the olfactory bulb than to the cerebral cortex of eulipotyphlans but not rodents, afrotherians or primates

Frontiers in Neuroanatomy, 2014
The olfactory bulb is an evolutionarily old structure that antedates the appearance of a six-layered mammalian cerebral cortex. As such, the neuronal scaling rules that apply to scaling the mass of the olfactory bulb as a function of its number of ...

Third-generation rabies viral vectors allow nontoxic retrograde targeting of projection neurons with greatly increased efficiency

Cell Reports: Methods, 2023
Summary: Rabies viral vectors have become important components of the systems neuroscience toolkit, allowing both direct retrograde targeting of projection neurons and monosynaptic tracing of inputs to defined postsynaptic populations, but the rapid ...

Cellular scaling rules for the brain of afrotherians

Frontiers in Neuroanatomy, 2014
Quantitative analysis of the cellular composition of rodent, primate and eulipotyphlan brains has shown that nonneuronal scaling rules are similar across these mammalian orders that diverged about 95 million years ago, and therefore appear to be ...

The human cerebral cortex is neither one nor many: Neuronal distribution reveals two quantitatively different zones in the grey matter, three in the white matter, and explains local variations in cortical folding

Frontiers in Neuroanatomy, 2013
The human prefrontal cortex has been considered different in several aspects and relatively enlarged compared to the rest of the cortical areas. Here we determine whether the white and gray matter of the prefrontal portion of the human cerebral cortex ...
