In this review the current knowledge of the anatomy, development and plasticity of the rodent
corticospinal tract is summarised. Recent technical advancements, especially in neuronal
tracing methods, have provided much new data concerning the anatomy of the corticospinal
tract. The rodent corticospinal axons project to the subcortical nuclei via collateral branches.
These collateral branches of corticospinal axons are formed by delayed interstitial budding
during early postnatal periods. Corticospinal neurons are generated in the ventricular zone …
