1. A mobile brain-based device for behaving in a real-world environment to integrate a visual scene, comprising: a. a mobile adaptive device having i. a visual input sensor for receiving visual information; ii. an auditory input sensor for receiving auditory information; and iii. an effector for enabling movement of said mobile adaptive device; b. a computer-based simulated nervous system corresponding to the cortical regions of a human brain for binding different visual features of an object within the visual scene, said computer-based simulated nervous system including i. a first neural area forming a visual system and responsive to visual input from said visual input sensor for producing visual stimuli, said first neural area corresponding to the ventral cortical pathway of the brain for producing visual stimuli, said first neural area including neural areas V 1 , V 2 , V 4 and IT being coupled in a pathway V 1 →V 2 →V 4 →IT; ii. a second neural area forming an auditory system and responsive to auditory input from said auditory input sensor for producing auditory stimuli; iii. a third neural area, analogous to an ascending neuromodulatory system, responsive to a real-world salient event experienced by the mobile brain-based device while being mobile in its real-world environment, for producing value stimuli; and iv. a fourth neural area, forming a tracking system and responsive to said auditory, visual and value stimuli, for controlling said effector to orient said mobile adaptive device towards the auditory and visual input information to said mobile adaptive device, said fourth neural area corresponding to the superior colliculus area of the brain; and c. wherein visual binding is achievable during real-world mobility of said mobile adaptive device through reentrant connectivity of neuronal units within each of said first, second, third and fourth neural areas, through reentrant connectivity between said first, second, third and fourth neural areas, and through the interaction of local processes, which are activities within each of said first, second, third and fourth neural areas, and global processes which create functional neural circuits formed during the real-world operation and having synchronous activity between said first, second, third and fourth neural areas.
