Impaired transmission in the corticospinal tract and gait disability in spinal cord injured persons [PDF]
, 2010 Rehabilitation following spinal cord injury is likely to depend on recovery of corticospinal systems. Here we investigate whether transmission in the corticospinal tract may explain foot drop (inability to dorsiflex ankle) in persons with spinal cord ...

MRI in ALS: Corticospinal tract hyperintensity [PDF]
Neurology, 2003 A 32-year-old woman with no family history presented with 12 months of progressive left upper limb weakness. Examination revealed moderate wasting and pyramidal weakness in all muscle groups in the left upper limb, especially the shoulder girdle and …

Task-specific modulation of corticospinal neuron activity during motor learning in mice
Nature Communications, 2023 Motor skill learning relies on the plasticity of the primary motor cortex as task acquisition drives cortical motor network remodeling. Large-scale cortical remodeling of evoked motor outputs occurs during the learning of corticospinal-dependent ...

Corticospinal and reticulospinal contacts on cervical commissural and long descending propriospinal neurons in the adult rat spinal cord; evidence for powerful reticulospinal connections [PDF]
, 2016 Descending systems have a crucial role in the selection of motor output patterns by influencing the activity of interneuronal networks in the spinal cord.

Is Remodelling of Corticospinal Tract Terminations Originating in the Intact Hemisphere Associated with Recovery following Transient Ischaemic Stroke in the Rat? [PDF]
PLoS ONE, 2016 Following large strokes that encompass the cerebral cortex, it has been suggested that the corticospinal tract originating from the non-ischaemic hemisphere reorganises its pattern of terminal arborisation within the spinal cord to compensate for loss of

Assessment of Motor Evoked Potentials in Multiple Sclerosis
Sensors, 2023 Transcranial magnetic stimulation (TMS) is a noninvasive technique mainly used for the assessment of corticospinal tract integrity and excitability of the primary motor cortices. Motor evoked potentials (MEPs) play a pivotal role in TMS studies.

Diffusion Tensor Imaging-Based Research on Human White Matter Anatomy
The Scientific World Journal, 2012 The aim of this study is to investigate the white matter by the diffusion tensor imaging and the Chinese visible human dataset and to provide the 3D anatomical data of the corticospinal tract for the neurosurgical planning by studying the probabilistic ...
