What factors affect axon growth?

growth of axons and factors that affect it play an important role in determining brain circuits. Molecular gradients and concentrations, as well as shooting patterns, help to determine the direction of axon growth and where this axon forms its synapses. Significant efforts in the scientific community are focused on cataloging and creating a comprehensive overview of all factors that determine the growth of axons. The process of axon growth and associated control of synapse formation that communicates in the brain directly with each other and how information is processed. They can be expressed as ligands on cellular surfaces or as freely floating, relaxed molecules that create molecular density in the brain. At certain concentrations, they have the ability to attract axons of specific cell types to grow and at other concentrations to act as repellents. This allows them to function as a guide during the phases of axon growth, but to avoid simply pulling all local axons to grow towards a cell releasing molecular instructions.

In the adage, other axon growth associations are still expressed, "cells that are shealing together." This means that the cells of certain types of classes or cells that process a certain class of information will have a determined probability of forming synapses with other cells in the motifs of the nerve circuits. This phenomenon creates repeated patterns of circuits in the brain that scientists can use to understand how the brain processes information.

very soon in cellular development, Neuron has many undifferentiated neurits. These cellular somatic processes remain unspecified until there are certain circumstances such as contact with other close cells or exposure to a certain molecule or growth factors that cause differentiation where one becomes axon and the remaining neurites on Soma cells evolve. When this happens, neurite that becomes axon begins to stretch and develop the characteristics of PodoBeling axon. These properties will include a lack of dendritic spines, a thinner appearance than other neurites and common arborization of the terminal.

During the development of the brain, axons also tend to grow in directions that are later cut as the body matures. This is considered an evolutionary return, because these inputs could have been used once, but they are no longer, in the same way as the human fetus develops the tail, but this characteristic will soon disappear. Although it might seem redundant to develop axons to be consistently cut back, we need to consider many factors that have determined the way the nerve circuits have been formed. A little apparent redundancy in development can have their own use at present out of scientific understanding.
