Description of part

The correspondence between what Streeter (1903), Castaldi (1923), and Berman (1968) identified as the NI in the human, guinea pig, and cat, and what Wyss et al. (1979) called NI in the rat is unclear. Based on connectional and histochemical evidence (N.S Canteras, personal communication) the NI of Wyss et al. and the central gray matter, pars alpha of Meesen and Olszewski (1949) appear to form parts of a single nucleus, which we have divided into compact (medial) and diffuse (lateral) parts, the latter corresponding to the pars alpha.

Part type

gray matter

Nomenclature

Swanson-1992

Endorsement

The approach used by the collator Mihail Bota is not endorsed by the author of the nomenclature.

Collator argument

The hierarchy was constructed and adapted according to the information found in the Rat Brain Atlas, Swanson 1992. We have considered three types of brain structures: grisea (neural masses), fiber tracts, and ventricles. The hierarchical tree was constructed by taking into account two criteria: the set of classes and subclasses of the basic cell groups and fiber systems of the rat CNS and the topological positions of structures relative to superstructures.
