Functional Trade-Offs in White Matter Axonal Scaling
TLDR
The heterogeneous white matter composition found in large brains reflects a metabolically constrained trade-off that reduces both volume and conduction time, and in select sets of communicating fibers, large brains reduce transmission delays and metabolic firing costs at the expense of increased volume. Expand
Cellular scaling rules for the brain of afrotherians
TLDR
The clade-specific characteristics that relate to the distribution of neurons along the surface of the cerebral cortex and to its degree of gyrification suggest that these characteristics compose an evolutionarily plastic suite of features that may have defined and distinguished mammalian groups in evolution. Expand
How to Build a Bigger Brain: Cellular Scaling Rules for Rodent Brains
TLDR
It is proposed that the faster increase in average neuronal size in cerebral cortex than in cerebellum as these structures gain neurons and the fast-increasing glial numbers that generate glial mass to match total neuronal mass are fundamental cellular constraints which lead to the relative expansion of cerebral cortical volume across species. Expand
The Neocortex of Indian River Dolphins (Genus Platanista): Comparative, Qualitative and Quantitative Analysis
TLDR
Taken as a whole, it appears that the neocortex of platanistids exhibits a considerable expansion of the auditory field, and even more than other toothed whales, they seem to depend on their biosonar abilities for navigation, hunting, and communication in their riverine habitat. Expand
The elephant brain in numbers
TLDR
The hypothesis that the larger absolute number of neurons in the human cerebral cortex (but not in the whole brain) is correlated with the superior cognitive abilities of humans compared to elephants and other large-brained mammals is supported. Expand
Cellular signatures in the primary visual cortex of phylogeny and placentation
TLDR
There is evidence for cellular signatures of phylogenetic divergence from the mammalian trend in primates and carnivores, as well as considerably divergent scaling patterns between the primate suborders, Strepsirrhini and Haplorrhini, that likely originated at the anthropoid stem. Expand
Comparative cytoarchitectural analyses of striate and extrastriate areas in hominoids.
TLDR
It is suggested that interspecific variability in the cytoarchitectural organization of visual system structures can arise independently of global brain and body size scaling relationships. Expand
Scaling of Inhibitory Interneurons in Areas V1 and V2 of Anthropoid Primates as Revealed by Calcium-Binding Protein Immunohistochemistry
TLDR
The findings suggest that modifications of specific aspects of inhibition might be critical to establishing the receptive field properties that distinguish visual areas and show that phylogenetic variation exists in the microcircuitry of visual cortex that could have general implications for sensory processing. Expand
Scaling laws in the mammalian neocortex: Does form provide clues to function?
TLDR
This work describes several morphological specializations at the cellular level that may constitute functional adaptations in the neocortex, and considers exceptional cases of neocortical morphology as a means of testing putative functional principles and developmental mechanisms. Expand
