interposed nucleus of the cerebellum
Acronym: ICb
The term interposed nucleus of the cerebellum denotes the nuclear mass lying between the fastigial nucleus and the dentate nucleus in the cerebellar white matter of non-primate mammals, such as the rat ( Swanson-1998 ) and the mouse ( Paxinos-2001 ). It is topologically equivalent to the combined globose nucleus and emboliform nucleus of the primate cerebellar nuclei ( Carpenter-1983 ).
     Anatomists segment the nucleus differently. In the Functional CNS - Rat it consists of two parts: the main part of the interposed nucleus and the parvicellular part of the interposed nucleus ( Swanson-2004 ). In a mouse brain atlas it consists of four parts based on separation of cell groups by fiber bundles: anteror, dorsolateral hump, posterior and posterior parvicellular parts ( Franklin-2008 ). In another atlas of the rat brain it consists of those four parts plus a dorsomedial crest part ( Paxinos-2009b ).
