This conference was instigated by a combination of factors: The nature of the problem, the wide spread occupational epidemiology reported on eye symptoms and eye fatigue in the workplace, and the organizers' awareness of the complexity of the scientific and clinical bases of knowledge that might be usefully applied. The introduction of new methods into system neurobiology provides new insights into how we receive and process information from the external world, and act upon it. New, non-invasive methods have opened the way to direct observation of the human brain in action. Due particularly...

To anyone who worked long on the functional organization of living systems, it seems obvious that the central problems arise from a multi plicity of closed loops Simultaneously active in the control of every act. Severally, they may be stable but, combined, they may crack up or break into schizogenetic oscillation. Whatever they are, linear or not, is beside the point, for in either case the same difficulty of analysis arises. Nor does it help our argument that we deal only with formal neurons or those having greater similitude to real ones. This limited Pitts and me, in 1943, to three...
