Paleoneurology

Paleonurological studies in the field of neuroanatomy and evolutionary phylogeny reveal the presence of residual features of the nervous system in fossil animals. The discovery of fragments of the nervous system in ancient times became the basis for the creation of paleoneurology.

Paleo-evolution studies the methods and results of the analysis of evolution based on the many finds of animals that lived long before the existence of modern human races. This area of ​​paleontology is closely related to anthropology. For paleoneutrophy, many different methods are used to study such ancient animals. The basis is made up of micro and macroscopic examinations, as well as subtle manipulations associated with fixation and preservation of remains. Even if after excavation the find remains in the earth’s layers for a long time, it can be recognized by the structure of bones and muscles. The remains of bone marrow and tissue of the nervous system are presented in the form of soft tissues that have undergone decay. This makes learning more difficult. The study of the structures of nervous tissue was performed with exceptional quality thanks to modern technologies. Histological analyzes are also carried out, which makes it possible to assess the condition of the nervous tissue. In difficult cases, studies are carried out on individual cells. In this case, a cell culture method is used. Neural analysis is necessary to build a complete picture of the structure of the nervous tissue of ancient organisms. An organic basis is needed to understand the complex processes inside neurons. Analysis of tissue remains can only be carried out in a laboratory; squeezing the brain out of fossil remains will not solve the problem. It is important for scientists to recreate a complete picture of the historical development of nervous tissue and understand not only the anatomy, but also the functional features. This type of research allows us to understand the differences between animals with developed and primitive nervous systems. The presence of bone fragments of an animal determines the presence of a nervous system, but from these fragments alone it is impossible to accurately determine the type of animal. Samples available for study are found in teeth, nerve trunks, and pterygoid processes. The bodies of neuroglial cells are also preserved, indicating the complex structure of the animal's nervous system. When studying the preserved details of nervous tissue, different forms of nerve endings, arteries, other blood vessels and collaterals are revealed. At the same time, researchers are faced with the problem of fixing fragments where soft tissue is not completely preserved. However, this approach
