The lateral reticular nucleus sends all of its projections to the cerebellum.
All of these efferent pathways are projected in an ipsilateral manner to the cerebellum, the most abundant of which are those to the vermis.
The afferent pathways to the LRN come from the spinal cord and higher brain structures.
Most of the afferents come from the ipsilateral dorsal horn of the spinal cord and project exclusively to the parts of the LRN that do not receive input from the cortex.
The spinal cord projections terminate mostly in the parvocellular region along with the adjacent magnocellular cells.
