2-Minute Neuroscience: Corticospinal Tract
December 6, 2015
In this video I discuss the corticospinal tract, a major tract that carries movement-related information from the motor cortex to the spinal cord. I discuss upper and lower motor neurons and trace the pathway the corticospinal tract takes from the cortex to the spinal cord, mentioning the major fiber bundles it is found in along the way like the cerebral peduncles and medullary pyramids. I describe the two branches of the corticospinal tract: the lateral and anterior corticospinal tracts, and I discuss their respective specializations. Finally, I cover the types of deficits that can appear when damage to the corticospinal tract occurs.
