The dorsal spinocerebellar tract (posterior spinocerebellar tract, Flechsig's fasciculus, Flechsig's tract) conveys proprioceptive information from the body to the cerebellum.

It is part of the somatosensory system and runs in parallel with the ventral spinocerebellar tract. Proprioceptive information is taken to the spinal cord where it meets the first order neuron in the Dorsal Root Ganglion,information then travels through the dorsal horn where it synapses with a second order neuron, this proprioceptive information travels up the spinal cord in the posterior funiculus ipsilaterally until it reaches the brainstem. At Brainstem level it desuccates in the medulla oblongata. It then reaches the Cerebellum where propriocaptive information is processed

This tract involves two neurons and ends up on the same side of the body.
