Two of the five sensory modalities, pain and temperature, cross sides at the anterior white commissure, reaching the contralateral side about two vertebral levels rostral to their origin. The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it ...
The axons of the tract cells cross over (decussate) to the other side of the spinal cord via the anterior white commissure, and to the anterolateral corner of the spinal cord (hence the spinothalamic tract being part of the anterolateral system). Decussation usually occurs 1-2 spinal nerve segments above the point of entry.
The ventral spinocerebellar tract will cross to the opposite side of the body first in the spinal cord as part of the anterior white commissure and then cross again to end in the cerebellum (referred to as a "double cross"), as compared to the dorsal spinocerebellar tract, which does not decussate, or cross sides, at all through its path.
White matter tracts within a human brain, as visualized by MRI tractography A nerve tract is a bundle of nerve fibers ( axons ) connecting nuclei of the central nervous system . [ 1 ] [ 2 ] [ 3 ] In the peripheral nervous system , this is known as a nerve fascicle , and has associated connective tissue .

The tract is bilateral: its fibers ascend predominately ipsilaterally, but a minority decussate in the anterior white commissure to ascend contralaterally. Second-order axons of this tract terminate by forming multiple synapses in the nuclei of the medullary, pontine, and mesencephalic reticular formation.
The anterior commissure (also known as the precommissure) is a white matter tract (a bundle of axons) connecting the two temporal lobes of the cerebral hemispheres across the midline, and placed in front of the columns of the fornix.
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
