Description of part

The cerebral cortex has been divided into areas that may(isocortical) or may not (allocortical) be fitted into a basic six-layered scheme (Vogt and Vogt 1919), numbered 1-6 here. These terms are preferred to the equivalent homotypical and heterotypical of the Vogt pupil, Brodmann (1909), and to the terms neocortical, archicortical, and paleocortical (Ariens Kappers 1909) all of which imply unsubstantiated phylogenetic and ontogenetic attributes (see Lorente de No 1934, Ebbeson 1980). The olfactory cortex (including superficial parts of the amygdala) and hippocampal formation form the allocortex, as interpreted here. A traditional approach to naming cortical areas, based on Brodmann work and ultimately general for all mammals, has been adapted here. For another scheme, idiosyncratic to the rat, see Zilles and Wree (1995). Names of the 6 isocortical layers from superficial to deep, would include: 1, molecular layer, 2, superficial supragranular pyramidal layer, 3, deep supragranular pyramidal layer, 4, granular layer, 5, infragranular pyramidal layer, and 6, polymorph layer.
