Hierarchical Features of Large-Scale Cortical Connectivity [PDF]

European Physical Journal B, v. 48, n. 4, p. 567-573, 2005, 2005
The analysis of complex networks has revealed patterns of organization in a variety of natural and artificial systems, including neuronal networks of the brain at multiple scales. In this paper, we describe a novel analysis of the large-scale connectivity between regions of the mammalian cerebral cortex, utilizing a set of hierarchical measurements ...

Labyrinthine Turing Pattern Formation in the Cerebral Cortex [PDF]

J. Theor. Biol. 217, 97-103, 2002, 2002
I propose that the labyrinthine patterns of the cortices of mammalian brains may be formed by a Turing instability of interacting axonal guidance species acting together with the mechanical strain imposed by the interconnecting axons.

Aberrant survival of hippocampal Cajal-Retzius cells leads to memory deficits, gamma rhythmopathies and susceptibility to seizures in adult mice

Nature Communications, 2023
Cajal-Retzius neurons number drastically decreases during postnatal life. Here, authors show that their programmed death is required for the construction of functional hippocampal circuits and memory with aberrant survival leading to gamma rhythmopathies

Investigation of the Mechanisms Underlying the Development and Evolution of the Cerebral Cortex Using Gyrencephalic Ferrets

Frontiers in Cell and Developmental Biology, 2022
The mammalian cerebral cortex has changed significantly during evolution. As a result of the increase in the number of neurons and glial cells in the cerebral cortex, its size has markedly expanded. Moreover, folds, called gyri and sulci, appeared on its

Neuroprotection in Cerebral Cortex Induced by the Pregnancy Hormone Estriol. [PDF]

, 2023
In multiple sclerosis (MS), demyelination occurs in the cerebral cortex, and cerebral cortex atrophy correlates with clinical disabilities. Treatments are needed in MS to induce remyelination. Pregnancy is protective in MS.

The chronoarchitecture of the cerebral cortex [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2005
We review here a new approach to mapping the human cerebral cortex into distinct subdivisions. Unlike cytoarchitecture or traditional functional imaging, it does not rely on specific anatomical markers or functional hypotheses. Instead, we propose that the unique activity time course (ATC) of each cortical subdivision, elicited during natural ...

Specific contribution of neurons from the Dbx1 lineage to the piriform cortex

Scientific Reports, 2021
The piriform cortex (PC) is a major cortical processing center for the sense of smell that receives direct inputs from the olfactory bulb. In mice, the PC consists of three neuronal layers, which are populated by cells with distinct developmental origins.

Cerebral cortex and blood transcriptome changes in mouse neonates prenatally exposed to air pollution particulate matter

Journal of Neurodevelopmental Disorders, 2021
Background Prenatal exposure to air pollutants is associated with increased risk for neurodevelopmental and neurodegenerative disorders. However, few studies have identified transcriptional changes related to air pollutant exposure.

Decreased density of pyramidal cells in the cerebral cortex, and Purkinje cells in the cerebellar cortex of Sprague-Dawley rats after being exposed to filtered kretek cigarette smoke

Journal of Biological Research, 2023
Filtered kretek cigarette smoke is a gas that contains solid components (particulates). Carcinogenic chemicals are present in this type of cigarette smoke. Furthermore, it is said that tobacco has a major negative impact on cerebral structure development,
