2-Minute Neuroscience: Corticospinal Tract

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.


Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Building on neuroscientist Marc Dingman’s popular YouTube series, 2-Minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks using real-life examples and Dingman’s own, hand-drawn illustrations.
