The dorsal spinocerebellar tract (posterior spinocerebellar tract, Flechsig's fasciculus, Flechsig's tract) conveys proprioceptive information from proprioceptors in the skeletal muscles and joints to the cerebellum. [3] It is part of the somatosensory system and runs in parallel with the ventral spinocerebellar tract.
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain , the pons , and the medulla oblongata . [ 1 ]
The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons, or basilar pons. Along with the dorsal surface of the medulla oblongata, it forms part of the rhomboid fossa – the floor of the fourth ventricle.
A cross-section of the pons divides it into a ventral and a dorsal area. The ventral pons is known as the basilar part, and the dorsal pons is known as the pontine tegmentum. [3] The ventral aspect of the pons faces the clivus, with the pontine cistern intervening between the two structures.

The tegmentum (from Latin for "covering") is a general area within the brainstem. The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. [ 1 ] It is located between the ventricular system and distinctive basal or ventral structures at each level.
→ reticulonuclear tract → lower motorneurons of the brainstem. [3] → reticulospinal tract → lower motor neuron of the spinal cord. [3] Medial habenular nucleus → fasciculus retroflexus → interpeduncular nucleus of midbrain → midbrain reticular formation → dorsal longitudinal fasciculus → autonomic pre-ganglionic neurons.

It extends across the dorsal tegmentum of all three parts of the brainstem, as well as reaching caudally into the upper cervical spinal cord levels. [ 3 ] : 451 Descending fibers arise from the superior colliculus in the rostral midbrain (for visual reflexes ), the accessory oculomotor nuclei in the rostral midbrain for visual tracking, and the ...
