[1] The spino-olivary tract is a non-specific indirect ascending pathway and is connected to the inferior olivary nuclei.

The axons enter the spinal cord from the dorsal root ganglia and terminate on unknown second-order neurons in the posterior grey column.

[2] The axons from the second-order neurons cross the midline and ascend as the spino-olivary tract in the white matter at the junction of the anterior and lateral columns.

[2] The axons end by synapsing on third-order neurons in the inferior olivary nuclei in the medulla oblongata.

The axons of the third-order neurons cross the midline and enter the cerebellum through the inferior cerebellar peduncle.
