      The Neuroanatomy and Neurophysiology of Consciousness 

		         Christof Koch
	  Professor of Computation and Neural Systems
               California Institute of Technology

   What is the relationship between the experience of visual perception
and the underlying neuronal activity in the visual system?  Dr. Francis
Crick and I propose that the function of visual awareness is to produce
an interpretation of the visual scene and to make it available, for a
sufficient time, to the parts of the brain that contemplate, plan and
execute voluntary motor outputs.  This suggest that the neurons that
express the neural correlate of consciousness must project from visual
cortices to the frontal lobe.  I will discuss electrophysiological,
clinical and psychophysical evidence for this hypothesis.   Finally, I
will discuss the implications that such a strategy has for designing
machine architectures that express some degree of awareness.

This Forum is OPEN to the public.
