Microcolumns in the cerebral cortex [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
Neuroanatomists from Cajal on (1) have searched in the cerebral cortex for units of structural organization that transcend the laminar pattern visible even to the untutored eye in Nissl-stained preparations. Many have commented on the vertical column-like arrays of cell bodies running orthogonal to the horizontal laminae that are particularly ...

Labyrinthine Turing Pattern Formation in the Cerebral Cortex [PDF]

open access: yes, 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.Comment: See home ...

Radial glial dependent and independent dynamics of interneuronal migration in the developing cerebral cortex. [PDF]

open access: yesPLoS ONE, 2007
Interneurons originating from the ganglionic eminence migrate tangentially into the developing cerebral wall as they navigate to their distinct positions in the cerebral cortex.

Regional astrocyte IFN signaling restricts pathogenesis during neurotropic viral infection [PDF]

open access: yes, 2017
Type I IFNs promote cellular responses to viruses, and IFN receptor (IFNAR) signaling regulates the responses of endothelial cells of the blood-brain barrier (BBB) during neurotropic viral infection.

Compensatory recombination phenomena of neurological functions in central dysphagia patients

open access: yesNeural Regeneration Research, 2015
We speculate that cortical reactions evoked by swallowing activity may be abnormal in patients with central infarction with dysphagia. The present study aimed to detect functional imaging features of cerebral cortex in central dysphagia patients by using

A novel micro-ECoG recording method for recording multisensory neural activity from the parietal to temporal cortices in mice

open access: yesMolecular Brain, 2023
Characterization of inter-regional interactions in brain is essential for understanding the mechanism relevant to normal brain function and neurological disease.

Regional differences in the coupling between resting cerebral blood flow and metabolism may indicate action preparedness as a default state. [PDF]

open access: yes, 2008
Although most functional neuroimaging studies examine task effects, interest intensifies in the "default" resting brain. Resting conditions show consistent regional activity, yet oxygen extraction fraction constancy across regions.

Gyrification of the cerebral cortex requires FGF signaling in the mammalian brain

open access: yeseLife, 2017
Although it has been believed that the evolution of cortical folds was a milestone, allowing for an increase in the number of neurons in the cerebral cortex, the mechanisms underlying the formation of cortical folds are largely unknown.

The impact of gamma-radiation on the cerebral- and cerebellar- cortex of male rats’ brain

open access: yesBrain Research Bulletin, 2022
This study aims to investigate the impact of gamma-radiation on the cerebral- and cerebellar-cortex of rat’s brain. Animals were whole-body exposed to 3 Gy, every 3 days, up to 9 Gy, and sacrificed 1 h, 1, 3, 7 & 10 days post the last radiation-dose.

Hierarchical Features of Large-Scale Cortical Connectivity

open access: yes, 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.
