Brain cells (also known as "glia" or "neuroglia") come in several types, and perform a number of critical functions, including structural support, metabolic support, insulation, and guidance of development. Neurons, however, are usually considered the most important cells in the brain. The property that makes neurons unique is their ability to send signals to specific target cells over long distances. They send these signals by means of an axon, which is a thin protoplasmic fiber that extends from the cell body and projects, usually with numerous branches, to other areas, sometimes nearby, sometimes in distant parts of the brain or body.
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".
