About the Book
"An electrochemical process is a chemical reaction that either causes or is caused by the movement of electrical current. These processes are a type of oxidation-reduction reaction in which one atom or molecule loses an electron to another atom or molecule. In electrochemical reactions, the atoms or molecules in the reaction are relatively far apart from each other compared to other reactions, forcing the electrons being transferred to travel a greater distance and thereby produce an electrical current. Many natural phenomena are based on electrochemical processes, such as the corrosion of metals, the ability of some sea creatures to generate electrical fields, and the workings of the nervous systems of humans and other animals. They also play an important role in modern technology, most prominently in the storage of electrical power in batteries, and the electrochemical process called electrolysis is important in modern industry.
The activities of nervous systems, from the simple reactions and instinctive behaviors found in even primitive animals to the complex learning and reasoning abilities of human beings, depend on electrochemical processes. Neurons use electrochemical processes to transmit information through the nervous system, allowing the nervous system to communicate with itself and with the rest of the body. To send a signal, chemical processes in the neuron generate an electrical impulse that is sent through an elongated structure called an axon until it reaches the synapse, the point of contact between the neuron and neighboring cells. At the synapse, the electricity causes the release of chemicals called neurotransmitters, which cross the synapse to the cell being signaled. The neurotransmitters then chemically bond with structures called receptors on the target cell, setting off further biochemical processes within it.
The ability of fish such as electric eels, stargazers, and torpedo rays to produce electric fields is the result of an electrochemical process. Electric fish possess specialized cells called electrocytes. Transport proteins bind with positive potassium and sodium ions in the cell and carry them away, building up an electric charge in the cell. When this electricity is needed, a part of the nervous system called the medullary command nucleus sends an electric impulse to other nerve cells, which triggers the release of the neurotransmitter acetylcholine. The neurotransmitter bonds with the acetylcholine receptors of the electrocytes, which triggers the release of the electrocytes' charge.
This book has been written in easy and fluent language expressive and self-explanatory labelled diagrams, concise but not too brief, written to the point starting from fundamentals and finishing to the most advanced and current concepts. All diagrams have been provided with detailed legends. Some diagrams have been drawn the author himself from the original source, while the remaining ones are quoted from the authentic works."
