What is consciousness? What is the mind? KIBO questions. Let me lay out some ideas, though. The initial processing of sensory data involves both sensations of external objects (afference) and internal expectations (reafference). These are merged via an integral transform (involving weightings defined on neural cell assemblies) to produce a distributed output signal. This can take two forms:chaos expressing novelty or distributed coherence (synchronization) signaling the existence of a known pattern. Detection of chaos can trigger an orienting reflex. The synchronized signal can either be processed simply as a signal that something known is being detected, or the associated sensory data can be processed further by downstream elements in a way similar to the processing of novel data. The gain of the system can be varied for optimum sensitivity. High gain tends to see artifacts as well as real patterns; low gain is insensitive. Hence, objects of interest to the organism are dual to these (continuously varying) patterns of more-or-less coherent dynamics in the brain--the mind. Note that these patterns are fundamentally semantic, although syntactic processing can be performed by the mind. Attention is the process by which these patterns emerge (are generated). The self is the internal pattern dual to the physically experienced body. Loss of consciousness is literally the loss of these patterns--loss of mind. This suggests that if we develop a capability of monitoring these coherent dynamics, we will have a way of objectifying the mind. -- Harry Erwin Internet: herwin@gmu.edu Just a dumb graduate student working on Katchalsky network models....
