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.

Posterior spinocerebellar tract: unconscious proprioceptive information from the lower part of trunk and lower limb. This tract originates at the ipsilateral Clarke's nucleus (T1-L1) and travels upward to reach the inferior cerebellar peduncle and synapses within the spinocerebellum (also known as the paleocerebellum).
Other afferent tracts are the ventral trigeminal tract, tectocerebellar fibers, and noradrenergic fibers from the locus coeruleus. The superior peduncle emerges from the upper and medial parts of the white matter of each cerebellar hemisphere [ citation needed ] and is placed under cover of the upper part of the cerebellum.
Inferior cerebellar peduncle is a thick rope-like strand that occupies the upper part of the posterior district of the medulla oblongata. The peduncles form the lateral border of the fourth ventricle , and form a distinctive diamond – the middle peduncle forming the central corners of the diamond, while the superior and inferior peduncles ...
The spinomesencephalic pathway, spinomesencephalic tract or spino-quadrigeminal system of Mott, includes a number of ascending tracts in the spinal cord, including the spinotectal tract. [ 1 ] [ 2 ] [ 3 ] The spinomesencephalic tract is one of the ascending tracts in the anterolateral system of the spinal cord that projects to various parts of ...
Descending tracts are pathways by which motor signals are sent from upper motor neurons in the brain to lower motor neurons which then directly innervate muscle to produce movement. The anterior corticospinal tract is usually small, varying inversely in size with the lateral corticospinal tract , which is the main part of the corticospinal tract .
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.
