Plexon (from " plexus," a term describing a network of nerve cells) is an American company that "invents, develops, and manufactures hardware and software that acquires, amplifies, records, and analyzes signals from individual brain cells." It is based in Dallas, Texas and is very close to the campus of Southern Methodist University with a satellite office in Brussels, Belgium. It primarily services academic researchers doing work in neuroscience and electrophysiology. Plexon equipment has been used in "areas of study including autism, prosthetic limb control for paralysis patients, and the effects of drugs on brain processing and memory." In addition, it also develops equipment and software for behavioral video tracking.
