Site and size of lesion predict post-stroke spasticity: A retrospective magnetic resonance imaging study

open access: yesJournal of Rehabilitation Medicine, 2020
Objective: Clinical parameters for prediction of post-stroke spasticity are well established. This report introduces 2 brain magnetic resonance imaging (MRI) parameters (infarct volume and topographic distribution) as post-stroke spasticity predictors ...

Сharacteristics of nervous system damage in children born with a very low and extremely low birthweight and perinatal hypoxic brain injury

open access: yesКубанский научный медицинский вестник, 2020
Aim. To determine the frequency of structural damage to the pyramidal tract in the region of crus posterius capsulae internae in children with a birthweight of less than one and a half kilograms with perinatal hypoxic damage to the nervous system using ...

Evaluation of Motor Neuron Injury in ALS by Different Parameters of Diffusion Tensor Imaging

open access: yesIEEE Access, 2020
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease involving upper and lower motoneurons selectively. The injury of lower motoneurons is closely related to the onset, progression and prognosis of ALS.

Circulating MicroRNAs as Diagnostic Biomarkers for Motor Neuron Disease

open access: yesFrontiers in Neuroscience, 2020
Motor neuron disease (MND) is a kind of neurodegenerative disease that selectively invades spinal cord anterior horn cells, brainstem motor neurons, cortical pyramidal cells and the pyramidal tract.

Tractography-guided surgery of brain tumours: what is the best method to outline the corticospinal tract?

open access: yesFolia Morphologica, 2021
BACKGROUND: Diffusion tensor imaging (DTI) is the imaging technique used in vivo to visualise white matter pathways. The cortico-spinal tract (CST) belongs to one of the most often delineated tracts preoperatively, although the optimal DTI method has not

Pontine tegmentum hematoma: a case report with the "one-and-a-half "syndrome without pyramidal tract deficit Hematoma tegmentar pontino: relato de caso com a síndrome "one-and-a-half" e sem déficit piramidal

open access: yesArquivos de Neuro-Psiquiatria, 1995
The author reports the case of a 54-year-old male patient with a pontine hematoma and with the one-and-a-half syndrome, cerebellar ataxia and no signs of pyramidal tract involvement.

Combining tractography and cortical measures to test system-specific hypotheses in multiple sclerosis. [PDF]

open access: yes, 2010
The objective was to test three motor system-specific hypotheses in multiple sclerosis patients: (i) corticospinal tract and primary motor cortex imaging measures differ between multiple sclerosis patients and controls; (ii) in patients, these measures ...

Effects of and TASK-like shunting current on dendritic impedance in layer 5 pyramidal-tract neurons. [PDF]

open access: yes, 2021
Pyramidal neurons in neocortex have complex input-output relationships that depend on their morphologies, ion channel distributions, and the nature of their inputs, but which cannot be replicated by simple integrate-and-fire models.

Single collateral reconstructions reveal distinct phases of corticospinal remodeling after spinal cord injury. [PDF]

open access: yes, 2012
Injuries to the spinal cord often result in severe functional deficits that, in case of incomplete injuries, can be partially compensated by axonal remodeling.
