On the subject of virtual reality (VR)
From the website CyberStage 2.1: Post Symbolism
Two areas of the brain, the most recent to evolve, which may be adversely affected or neglected by VR-simulated consciousness are the areas mapped and named by Brodmann Areas 39 and 40.
Area 39 is a neurological hub wherein one human sense is translated into another, into what are called sensory cross-modalities or synaesthetic precepts. Common comprehension of the world is filled with an infinity of such analogical arrangements; in fact, the world wouldn't be comprehensible without them. The fact that VR technology may be able to "grow eyes on the ends of our fingertips" and that cognitive engineers are attempting currently to do just that could cause Area 39 much "simulation sickness." Our own bodies are already doing as much and more; we already have eyes on the ends of our fingertips.
In direct, instant and parallel collaboration with Area 39 is Brodmann's Area 40, perhaps the seat of humanity's greatest inventions: Tools, Languages and Abstract Symbols (writing and numbers). It could be said to be the seat of the symbolic, because the pure symbolic would not be possible without it. Our mind/brain/body holistically contributes to a recreation of an abstract sense of reality. We are already virtual reality engines of a quite unprecedented order and design. Lanier's VR is nothing more or less than a delightfully dangerous toy theatre for further abstraction.
Area 40 helps to determine symbolic analogies for the sensory analogies of Area 39. It is the area which counts names out from what is no longer sensory chaos and sensory catastrophe. Both areas contrive with the other higher cortical faculties (which include, by extension, the general, external community) to create an absolute sensibility for context, meaning and government. But what will context, meaning and government be if the higher cortical faculties are decorticulated or dissociated? What will the resultant "experience" or psychological and sociological impact be? Will we, in fact, want to communicate such "experience?"
