You just awakened me that our nerves, and body in general, work more like a network than I cared to analyze. What other kinds of similarities can we gleam from this analog? Have those who work on digital networks made any useful discoveries from how the body and brain network? I vaguely recall a few things in which digital communication has learned a bit from animal communications and language itself but can't recall exact sources; brain like a sponge, it leaves as easily as it soaks up.
