The corticospinal or pyramidal tract is a collection of axons that travel between the cerebral cortex of the brain and the spinal cord. The corticospinal tract mostly contains motor axons. It ac...

The lateral corticospinal tract (LCST) is the most important pathway we have for making voluntary movements and is one of, if not THE, most important pathways in clinical neurology.

Lateral corticospinal tract axons also end upon spinal cord neurons that do not directly innervate muscle, but instead synapse upon lower motor neurons. Such cells are called interneurons. A pathway involving a lateral corticospinal axon, an interneuron and a lower motor neuron is disynaptic.

(Fictional, don't look it up.) Likewise, if there is a lateral corticospinal tract, there must also be a medial one. Indeed there is, only it is called the anterior corticospinal tract. Take comfort in the fact that it does actually lie medially.

PURPOSE: To prospectively evaluate several diffusion-tensor magnetic resonance (MR) imaging indexes (mean diffusivity [MD], fractional anisotropy [FA], and eigenvalues) of corticospinal tract impairment in patients with progressive muscular atrophy (PMA) and patients with amyotrophic lateral sclerosis (ALS).

Amyotrophic lateral sclerosis (ALS) is a predominantly clinical and electromyographic diagnosis. Conventional MRI reveals atrophy of the motor system, particularly the pyramidal tract, in the advanced stages but does not provide a sensitive measure of disease progression.

; The cortex directs motor activity through 2 pathways, the lateral corticospinal tract and the anterior corticospinal tract. ... The lateral corticospinal tract is the larger of the 2 pathways. The fibers descend from the cortex and go through the brainstem, and are found within the pyramids of the medulla.
