The cortex of the palaeopallium; the phylogenetically ancient part of the cerebral cortex that is involved in olfactory function (limited, in higher mammals, to the pyriform lobe).

1909 C. U. A. Kappers in Arch. Neurol. & Psychiatry 4 162 Just as in the pallium there can be distinguished three territories according to the connections which they exhibit, so the cortical structures occurring in them should be distinguished, according to the same principle, into a palæo-cortex, archi-cortex and neo-cortex.
1947 H. C. Elliott Textbk. Nerv. Syst. vii. 87/1 This first, or paleocortex..is soon overshadowed by the development of a general, or neocortex.
1996 Proc. National Acad. Sci. U.S.A. 93 15440/1 Motifs of neural circuitry seem surprisingly conserved over different areas of neocortex or of paleocortex, while performing quite different sensory processing tasks.
