Description of part

Definitions of the cerebrum have changed over the years, at one time it referred to the netire brain (that part of the CNS within the cranium). The term now commonly (though not universally) refers to the cerebral hemispheres or endbrain, that part of the cerebral hemispheres refers to the cerebral hemispheres or endbrain, that part of the neural rtube derived from the lateral ventricular neuroepithelium. Based on the embryological data reviewed in Alvarez-Bolado et al. (1995) and Alvarez-Bolado and Swanson(1996), the cerebrum contains two major subdivisions: cerebral cortex and basal nuclei or ganglia. Note that the term amygdala and septal region no longer appears as major subdivisions of the endbrain, they are arbitrarily defined regions that contain heterogeneous nuclei and/or cortical areas

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.
