	Lateral Corticospinal Tract
		The lateral corticospinal tract is the larger of the 2 pathways.
		In the lowermost medulla, the fibers cross, and descend as the lateral corticospinal tract.
		Some of the fibers of the lateral corticospinal tract terminate directly on the motor neurons (anterior horn cells) of the spinal cord, particularly those involved in fine motor control of the fingers and hand.

	Motor neurone disease - Wikipedia, the free encyclopedia
		The latter projection is called the corticospinal tract.
		Degeneration of the corticospinal tracts, as well as of the neurons in the motor strip of the cerebral cortex is known.
		Lateral identifies the areas in a person's spinal cord where portions of the nerve cells that are affected are located.

	Medical Neurosciences
		It is important to remember that damage to the corticospinal fibers rostral to the pyramidal decussation results in contralateral motor deficits, while lesions in the spinal cord (i.e., caudal to the decussation) result in ipsilateral deficits.
		This is because the lateral corticospinal tract influences the musculature on the same (ipsilateral) side of the body.
		Cerebrovascular accidents (“strokes”) commonly damage the corticospinal tract in the motor cortex or the posterior limb of the internal capsule (a compact bundle of axons through which almost all neural traffic to and from the cortex passes).

	THE BRAIN FROM TOP TO BOTTOM
		The other descending pyramidal tract, the corticospinal tract, stimulates the motor neurons in the spinal cord that are responsible for moving the body's axial muscles, as well as the arms and legs.
		Next, at the junction between the medulla and the spinal cord, the fibres of this lateral corticospinal tract cross the midline and continue their descent on the opposite side of the spinal cord.
		This ventral corticospinal tract is composed 10 to 20% of cortical axons.

	SC 4. Lateral Corticospinal Tract - Pathway (Site not responding. Last check: 2007-10-26)
		Cells in the cerebral cortex, especially the motor cortex (area 4; precentral gyrus) possess very long axons that descend through an extensive region of the brain to eventually reach the spinal cord.
		These fibers, which are now called the lateral (they are in the lateral funiculus) corticospinal tract (LCST), innervate neurons in the spinal cord along its entire length.
		Descending fibers in the LCST are somatotopically organized such that the most medially located fibers in the tract terminate before (rostral to) the more the laterally placed fibers.

	MedlinePlus Medical Encyclopedia: Babinski's reflex
		In people more than 2 years old, the presence of a Babinski's reflex indicates damage to the nerve paths connecting the spinal cord and the brain (the corticospinal tract).
		Because this tract is right-sided and left-sided, a Babinski's reflex can occur on one side or on both sides.

		Decussating component (about 90% of total) of the corticospinal projection that originates in the motor cortical areas of the posterior frontal lobe and the postcentral gyrus.
		The lateral corticospinal tract is located in the lateral white column of the spinal cord and terminates in the lateral portion of the ventral horn, where it governs the lower motor neuronal pools that control the distal extremities.
