Electrical conductivity plays a pivotal role in the life of organisms. Processes, such as neural information transfer, which allows a living organism to receive information and respond to it within the shortest time possible, are the basis of electrical conductivity. However, electrical conductivity is not only responsible for transmitting information. It provides living organisms the capability to encode this information, execute control processes and launch a complex system of reflex-related, behavioral and mental processes. Electrical conductivity is responsible for the control over all the functional systems of our body. An in-depth study of the electrical activity of the body will allow us to make an important conclusion on the presence of a functional control system in malignant tumors. A deep understanding of the basics of electrical stimulation and signal conduction will give us insights into the sphere of control and synchronization system within our central processor (brain) and other functional systems that we need for the proper functioning of human body; these systems are also capable of altering the natural physiological functioning of the body.
