Arch NeurPsych. 1926;16(4):451-470. doi:10.1001/archneurpsyc.1926.02200280059007
Abstract

As suggested in the previous article the phylogenetic translation of the centers for various sensory functions from the lower levels (mid-brain nuclei) to the cerebral mantle does not occur at one time. The first true forebrain structures to be developed in the animal series are devoted to the function of olfaction, and apparently this cortex is another illustration that certain of nature's structural experiments in the lower animals are incorporated in the higher without great modification. Thus the cortices serving olfaction in the mammalia are characterized by a very different cyto-architectonic design from that of the rest of the cerebral mantle. To this phylogenetically old cortex is given the descriptive name of the archipallium. All the rest of the mantle is formed by minor modifications of a single more recent pattern and is known as the neopallium. Figure 1, which is taken from Edinger, shows the comparative extent of
