1. A mobile brain-based device for navigating in a real-world environment, comprising: a) a mobile adaptive device having sensors for sensing multi-modal information in the real-world environment; b) a simulated nervous system for receiving and processing the multi-modal information sensed by the sensors and, in response, for outputting information to control movement of said mobile adaptive device in the environment; and c) wherein said simulated nervous system includes sensor input streams, an output motor stream, and a neural area analogous to the hippocampus and coupled to said sensor input streams and to said output motor stream of the simulated nervous system.
