Axons And Consciousness

Several contemporary theories of consciousness give a prominent place to axons. At a large-scale global level, the theory of neuronal group selection proposes that selectionist (as opposed to instructionist) mechanisms govern the formation, adaptation, and interactions of local collections of neuronal groups. Group activity is cojoined or correlated in what is viewed as a dynamic process brought about by reentrant connections. Reentry implies reciprocal feedforward-feedback networks, but the concept is also compatible with the axonal networks in aggregate. A key component is the sheer density of the connectional plexus, where vast numbers of combinations can be effectuated by the massively parallel organization in space and time.
