Noninvasive stimulation of the human corticospinal tract

Journal of Applied Physiology, 2004
Spinal tracts can be stimulated noninvasively in human subjects by passing a high-voltage stimulus between the mastoids or by magnetic stimulation over the back of the head. The stimulus probably activates the corticospinal tract at the cervicomedullary junction (pyramidal decussation) and evokes large, short-latency motor responses in the arm muscles.

Development of corticospinal tract fibers and their plasticity I: Quantitative analysis of the developing corticospinal tract in mice

Brain and Development, 1996
This study was undertaken to elucidate ultrastructurally and quantitatively the development of the corticospinal tract (CST) axons of mouse at the intumescence level of the cervical cord. An anterograde HRP study showed that the CST was located at the ventral one-third of the dorsal funiculus, and a few HRP-positive fibers were noted at the medialmost ...

Treatment planning with corticospinal tract

Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002
BOLD fMRI information has been integrated into radiation treatment planning to identify and avoid the eloquent cortices adjacent to a brain tumor. However, BOLD fMRI is essentially restricted to locate the activation in the cortical area. The white matter appears to be more susceptible to damage during the treatment by the radiation.

Growth and Maturation of the Rat Corticospinal Tract

1982
Publisher Summary This chapter discusses growth and maturation of the rat corticospinal tract. The development of the rat corticospinal tract has attracted attention in the past mainly because its late, largely postnatal development could be correlated with the maturation of certain forms of motor behavior.

Dual organization of motor corticospinal tract in the cat

Neuroscience Letters, 1977
Abstract The location of the cell bodies of the corticospinal neurons which distribute fibers to the cervical and the lumbar cord has been determined by means of the retrograde axonal transport of horseradish peroxidase. Two different types of cortical zones could be distinguished, i.e.

Projections and termination of the corticospinal tract in rodents

Experimental Brain Research, 1971
An examination of the precise mode of termination of the corticospinal system in the spinal cord of rodents has been conducted by use of light and electron microscope methods. This study confirms the position of the normal corticospinal tract in rodents in the ventralmost portion of the dorsal column white matter.

The corticospinal tract: Evolution, development, and human disorders

Developmental Neurobiology, 2016
ABSTRACT The corticospinal tract (CST) plays a major role in cortical control of spinal cord activity. In particular, it is the principal motor pathway for voluntary movements. Here, we discuss: (i) the anatomic evolution and development of the CST across mammalian species, focusing on its role in motor functions; (ii) the molecular ...

THE CORTICOSPINAL TRACTS IN MAN

Brain, 1990
The course, location and relations of the corticospinal tracts within the spinal cord of man are demonstrated on the basis of cases with lesions above the spinal cord restricted to the corticospinal tracts, of motor neuron disease, and of anterolateral cordotomies; control cases were of normal spinal cords.

Intraoperative neurophysiology of the corticospinal tract

1998
Interventions that directly or indirectly put the spinal cord at risk are considered as particularly challenging for the neurosurgeon, the interventional neuroradiologist, the orthopedic surgeon, the vascular surgeon and the clinical neurophysiologist.

Involvement of the corticospinal tract in the control of human gait

2011
Given the inherent mechanical complexity of human bipedal locomotion, and that complete spinal cord lesions in human leads to paralysis with no recovery of gait, it is often suggested that the corticospinal tract (CST) has a more predominant role in the control of walking in humans than in other animals.
