Description[edit | edit source]
The corticospinal tract contains bundles of axons which originate in the cerebral cortex and descend to synapse within the brainstem or spinal cord. The neurones are called "upper motor neurones". [1]
Anatomy[edit | edit source]
Origin[edit | edit source]
- 60 % fibres originate from the primary motor area, the premotor area, and the supplementary motor area of the frontal lobe
- Other fibres originate from the primary
sensory area, the parietal cortex and the parietal operculum [1]
