Diffusion Tensor Tractography of the Brainstem Pyramidal Tract: A Study on the Optimal Reduction Factor in Parallel Imaging

open access: yes대한영상의학회지, 2016
Purpose Parallel imaging mitigates susceptibility artifacts that can adversely affect diffusion tensor tractography (DTT) of the pons depending on the reduction (R) factor. We aimed to find the optimal R factor for DTT of the pons that would allow us to

An atlas of white matter anatomy, its variability, and reproducibility based on constrained spherical deconvolution of diffusion MRI

open access: yesNeuroImage, 2022
Virtual dissection of white matter (WM) using diffusion MRI tractography is confounded by its poor reproducibility. Despite the increased adoption of advanced reconstruction models, early region-of-interest driven protocols based on diffusion tensor ...

The dendritic density field of a cortical pyramidal cell [PDF]

open access: yes, 2012
Much is known about the computation in individual neurons in the cortical column. Also, the selective connectivity between many cortical neuron types has been studied in great detail.

Diffusion tensor MR imaging tractography of the pyramidal tracts and corpus callosum in children with right-sided congenital hemiparesis: A case report

open access: yes, 2010
This study used diffusion tensor tractography to evaluate the diffusion parameters of the corpsus callosum and asymmetry in the diffusion parameters of the corticospinal tracts in children with congenital hemiparesis.

The pyramidal syndrome and the pyramidal tract: a brief historical note [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2011
The discovery of the pyramidal syndrome and tract is briefly reviewed with emphasis on a few key historical aspects. The pursuit of the relationship between the lateralized deficits resulting from contralateral head trauma begins in the fourth century BC with the Hippocratic School and continues until the present day.

Adenosine A1 receptor activation mediates the developmental shift at layer 5 pyramidal cell synapses and is a determinant of mature synaptic strength [PDF]

open access: yes, 2013
During the first postnatal month glutamatergic synapses between layer 5 pyramidal cells in the rodent neocortex switch from an immature state exhibiting high probability of neurotransmitter release, large unitary amplitude and synaptic depression to a ...

Ultrastructural investigation on bovine Brunner's glands

open access: yesTranslational Research in Anatomy, 2019
Brunner’s glands are branched tubulo-acinar glands principally located within the lamina propria and the submucosa of the small intestine of mammals. Previous histochemical studies of Brunner’s glands in cattle have shown that the glandular lobules can ...
