1. A system for information processing, comprising: a plurality of signal processing elements connected to communicate with one another and configured to produce at least one output signal in response to at least one input signal; and a plurality of processing junctions disposed to interconnect said plurality of signal processing elements to form a network, wherein each of said processing junctions receives and processes a prejunction signal from a first signal processing element in said network based on at least one internal junction process to produce a junction signal that constantly varies with at least one parameter of said prejunction signal.
