corticospinal tracts
nerve fibers in these spinal cord motor tracts have their cell bodies in the cerebral cortex. Some have crossed to the opposite side of the cord from their side of origin, some are direct.

30-32) TcMEPs are useful because they evaluate integrity at the level of the cortex, corticospinal tract, and nerve roots.
It has been suggested that this method is not sensitive enough, as subtle deficits in the corticospinal tract, which may result in postoperative motor deficits, may not be detected.
The I-wave is generated from the indirect activation of the corticospinal tract via synaptic activity.
The multiple-ROI method allows discrete visualization of known anatomic tracts that pass through high-branching areas, such as the corticospinal tract as it passes through the brainstem, at the expense of nonvisualization of any associated branching tracts.

Clearly, knowledge of the location of the corticospinal tract in such a case would be advantageous, since the neurosurgeon would not have to perform a craniotomy, operate on the brain, and perform direct white matter stimulation only to discover that the tumor is inoperable.
For example, one can determine the location of the corticospinal tract or the thalamocortical tract and differentiate these tracts from all other white matter tracts in the corona radiata.
The fibers that decussate are called the lateral corticospinal tract or the lateral pyramidal tract.
Pyrimidal corticospinal tract educational aid was designed to fulfill the above objectives with the use of three dimensional model and computer aided animation mimicking the conduction of nerve impulses along the motor pathway.
However 44 students in test group were allowed to use the Pyrimidal corticospinal tract educational aid (both the model and computer animation) during their small group discussion time.
We studied OCT in subjects with MS of varying disease durations and with no exposure to DMTs to test the hypothesis that in untreated MS, RNFLt loss occurs both over the course of disease and in parallel with corticospinal tract dysfunction reflecting CNS neurodegeneration.
Corticospinal tract dysfunction as captured by EDSS also correlated with disease duration ([r.
