A ventral uncrossed corticospinal tract in the rat [PDF]

Experimental Neurology, 1980
By studying cross-section autoradiograms of the spinal cord with dark field microscopy we demonstrated a ventral uncrossed corticospinal tract in the rat. Corticospinal fibers were labeled by the slow axoplasmic flow of a minute volume of high specific activity tritiated proline injected directly into the motor sensory cortex.

Effects of lipopolysaccharide-induced inflammation on expression of growth-associated genes by corticospinal neurons [PDF]

BMC Neuroscience, 2006
Background Inflammation around cell bodies of primary sensory neurons and retinal ganglion cells enhances expression of neuronal growth-associated genes and stimulates axonal regeneration.

Rejuvenation of corticospinal neurons enhances rehabilitation-associated corticospinal tract axon sprouting and functional recovery post photothrombotic ischemic stroke in mice. [PDF]

Genes Dis
Spontaneous recovery following an ischemic stroke is often limited, largely attributed to age-related decline in neuroplasticity. To overcome this, we demonstrated that ectopic expression of a cocktail of transcriptional factors (Oct4, Sox2, and Klf4 ...

Corticospinal tract structure and excitability in patients with anterior cruciate ligament reconstruction: A DTI and TMS study

NeuroImage: Clinical, 2020
Background: Underlying neural factors contribute to poor outcomes following anterior cruciate ligament reconstruction (ACLR). Neurophysiological adaptations have been identified in corticospinal tract excitability, however limited evidence exists on ...

Corticospinal tract structure and descending motor output following anterior cruciate ligament reconstruction: an exploratory multimodal neuroimaging assessment. [PDF]

Front Hum Neurosci
BackgroundFunctional and structural differences in the central nervous system, including higher motor cortex activation, lower corticospinal excitability, and smaller corticospinal tract volume have been proposed as potential contributors to persistent ...

Human corticospinal tract lateralization at the height of the internal capsule is not related to handedness. [PDF]

Sci Rep
Evaluating the integrity of the corticospinal tract at the height of the posterior limb of the internal capsule with a lateralization index has been applied to predict upper limb motor recovery after stroke in numerous diffusion tensor imaging studies ...

Enhancing m6A modification in the motor cortex facilitates corticospinal tract remodeling after spinal cord injury

Neural Regeneration Research
Spinal cord injury typically causes corticospinal tract disruption. Although the disrupted corticospinal tract can self-regenerate to a certain degree, the underlying mechanism of this process is still unclear.

Quantitative measures of walking and strength provide insight into brain corticospinal tract pathology in multiple sclerosis

NeuroImage: Clinical, 2017
At least 85% of individuals with multiple sclerosis report walking dysfunction as their primary complaint. Walking and strength measures are common clinical measures to mark increasing disability or improvement with rehabilitation.

Age-related differences in agility are related to both muscle strength and corticospinal tract function. [PDF]

Physiol Rep
Agility is essential for “healthy” aging, but neuromuscular contributions to age‐related differences in agility are not entirely understood. We recruited healthy (n = 32) non‐athletes (30–84 years) to determine: (1) if aging is associated with agility ...
