1. Paleocortex

   In anatomy of animals, the paleocortex, or paleopallium, is a region within the telencephalon in the vertebrate brain. This type of cortical tissue consists of three cortical laminae (layers of neuronal cell bodies). In comparison, the neocortex has six layers and the archicortex has three or four layers. Because the number of laminae that compose a type of cortical tissue seems to be directly proportional to both the information-processing capabilities of that tissue and its phylogenetic age, paleocortex is thought to be an intermediate between the archicortex (or archipallium) and the neocortex (or neopallium) in both aspects.The paleocortex (or paleopallium) and the archicortex (or the archipallium) of the cerebral cortex together constitute the mammalian allocortex or the heterogenetic cortex. The distinction for what is called neocortex or isocortex, which comprises most of the human brain (about 90%), is made from the number of cellular layers that the structure comprises. Neocortical tissue comprises six distinct cell layers, not seen in paleocortical tissues either in adult or developing stage. In humans the paleocortex is exemplified in the olfactory cortex. For most vertebrates, the olfactory bulb is the main feature of the paleocortex, even though the division is virtually unused outside of a mammalian context.

1. paleocortex

   Paleocortex is a type of cortical tissue in the brain that is involved in olfactory processing and evolved earlier (is phylogenetically older) than other types of cortex. It is found in the most primitive regions of the brain and is characterized by having three cortical layers, unlike the six found in neocortex, which is the most developed part of the cerebral cortex.

1. Paleocortex

   Paleocortex is a type of cortical tissue that consists of either four or five cortical laminae. It has fewer laminae than neocortex, which has six, but more than archicortex, which has three. Paleocortex, along with archicortex and periallocortex, is a type of allocortex. Because the number of laminae that compose a type of cortical tissue seems to be directly proportional to both the information-processing capabilities of that tissue and its phylogenetic age, paleocortex is thought to be an intermediate between neocortex and archicortex in both aspects.
