What is paleocortex?

paleocortex is a structure in the brain. It is primarily associated with the organism or smell. It is part of the cortex, an important part of the central nervous system of all mammals, including human beings. The "paleo" prefix, which means "old", refers to the fact that this part of the cortex was created in an evolutionary history of mammals and their ancestors before the development of neocortex or the "new" bark that is part of the brain that is located only in mammals connected with higher mental functions such as reasons, and /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// bark 'its itself They contain the furthest layer of the brain. It also contains Neocortex and Archikortex. Paleocortex and Archicortex, which is involved in memory and emotions, are also referred to as Alocortex.

Paleocortex is made of three to five horizontal layers of nerve cells in the gray mass of the brain. It contains several components related to olfactory, including olfactory bulb, olfactory tubercle and piriform cortex. These structures receive sensory information from the olfactory epithelium, the type of tissue in the nasal cavity that detects the presence of chemicals and interprets them. They may also have other roles; For example, there is some research that suggests that the olfactory tubercle plays a role in the brain removal system. The olfactory system in the paleocortex is closely associated with parts of the limbic system, such as hippocampus and amygdala, which are important for memory and emotions.

In the human brain, Paleocortex represents only a small percentage of bark compared to many other mammals, with neocortex containing the vast majority of human cortex. This is because human intelligence requires in proportion to a larger neocortex to make difficult reasoning. People are also less spoThey fly to their smell than many other mammals, which reduces the importance of the olfactory system and more depends on their sense of supervision, which is processed in the mammal brain in the part of the neocortex called the visual bark. The compromise is that the smell of human feeling is significantly lower than in many other animals. Our brains can only process a small fraction of the amount of entry that can process the brain of an animal like a dog, and in our noses we have less scents.
