What are microcurrents?
Microcurrents, in their simplest explanation, are low level electrical current either generated by or conducted by the body. Basically, the small amounts of electricity that pass in and around the cells.
The body naturally generates electricity in the process of producing energy required for muscle movement and nerve impulses. It is the body’s own electrical system that provides the voltage for ionic exchanges across the cell membranes allowing for cell functions including the intake of nutrients from the blood, removal of cellular waste and movement of impulses along nerve pathways. The flow of these tiny electrical signals is also essential for healthy cell function and cell-to-cell communication. In the event of injury or disease there is signal disruption that obstructs the pathways of intercellular communication.
They conduct electricity, create electrical fields, and are powered by a very low level of electrical voltage known. A unique bi-polar membrane surrounds each cell and serves as medium that separates intracellular and extracellular fluids. Imbedded in this membrane are channels that allow for communications in and out of the cell. The opening and closing of these channels are carefully regulated in order to influence cell function under normal and pathological conditions. Single molecules or complexes of molecules within the channels allow for the passage of positively and negatively charged atoms (ions) such as sodium, potassium, chloride and calcium. The voltage difference in electrical potential across cell membranes is called membrane potential (Cooper, Hausman, Ch 13). Membrane potential arises from the interaction of ion channels and ion pumps that are embedded in the membrane, which maintain different ion concentrations on the intracellular and extracellular sides of a cell membrane.
