Membrane potential function as a battery, providing power to operate a variety of "molecular devices" embedded in the membrane. Second, in electrically excitable cells such as neurons and muscle cells, it is used for transmitting signals between different parts of a cell. Signals are generated by opening or closing of ion channels at one point in the membrane, producing a local change in the membrane potential. This change in the electric field can be quickly affected by either adjacent or more distant ion channels in the membrane. Those ion channels can then open or close as a result of the potential change,
Imagined speech intent of providing a foundation for synthetic telepathy. According to DARPA, the project “will allow user-to-user communication on the battlefield without the use of vocalized speech through neural signals analysis. The brain generates word-specific signals prior to sending electrical impulses to the vocal cords. These imagined speech signals would be analyzed and translated into distinct words allowing covert person-to-person communication.” DARPA's program outline has three major goals: The process for analyzing subjects' "silent speech" is composed of recording subjects’ brain waves, and then using a computer to process the data and determine the content of the subjects' "covert speech".
