Timeline of brain evolution, on animals. Brain dont left any fossil, so knowing the paths that of the brain evoltuion is not a easy task, the study of brain evoltuion relies on

observable through the fossil record, animal phylogeny, as well as during the stages of mammalian and human prenatal development, states that the mammalian brain's evolution...............

cerebellum evolution

[edit]

The cerebellum is of archipalliar phylogenetic origin. The pallium is a term for gray matter that forms the cortex. The archipallium is the one of the most evolutionarily primitive brain regions. The circuits in the cerebellar cortex look similar across all classes of vertebrates, including fish, reptiles, birds, and mammals (e.g., Fig. 2). This has been taken as evidence that the cerebellum performs functions important to all vertebrate species.

Limbic system Evolution

[edit]

In evolutionary terms, the limbic system is among the oldest parts of the brain and is related to the olfactory lobes. It can be found in fish, amphibians, reptiles and mammals.

neocortex Evolution

[edit]

With respect to evolution, the neocortex is the newest part of the cerebral cortex (hence the name "neo"); the other parts of the cerebral cortex are the paleocortex and archicortex, collectively known as the allocortex. The cellular organization of the allocortex is different from the six-layer structure mentioned above. In humans, 90% of the cerebral cortex is neopallium.

The six-layer cortex appears to be a distinguishing feature of mammals: It has been found in the brains of all mammals but not in any other animals. There is some debate[1][2], however, as to the cross-species nomenclature for neocortex. In avians, for instance, there are clear examples of cognitive processes that are thought to be neocortical in nature, despite the lack of the distinctive six-layer neocortical structure. In a similar manner, reptiles, such as turtles, have primary sensory cortices. A consistent, alternative name has yet to be agreed upon.
