The term postcerebellar and precerebellar nuclei refers to seven nuclei in the midbrain, pons, and medulla that constitute a functional part of the subcortical motor system of the cerebrospinal trunk. They include the red nucleus, ventral pontine gray, inferior olivary complex, lateral reticular nucleus, linear nucleus of the medulla, ventral paramedian reticular nucleus, and parasolitary nucleus. Functionally they are part of the subcortical motor system ( Swanson-2004 ).
