A branch of chemistry devoted to the study of chemical changes generated by electrical currents and the production of electricity by chemical reactions involving ions in solution, including electrolysis and electric cells. Given that all chemical reactions involve changes in the electronic structure of atoms, it therefore follows that all reactions (including organic ones) are electrochemical in nature, something that was not recognized in the past. The techniques of electrochemistry are widely used in the neurosciences. Examples include electrochemical microelectrode techniques for measuring chemical messengers released from cells in tissue or from individual cells in culture (e.g., dopamine, norepinephrine, epinephrine, serotonin), and in the measurement of metabolic substances in brain tissues (e.g., oxygen, ascorbate, uric acid).
