E-2 Finite-State Brain to E-1 Infinite-State Brain
My Papers on origins of REM in dreaming, phasic transients, loss of external clock
and resultant change of brain circuitry from (hardwired) finite-state to a (softwired)
ANALOG-ous to Infinite-State circuit are published elsewhere. Some of this material
which tries to prove Globus’ Real-Time hypothesis and is from my time at Stirling
University Centre for Cognitive and Computational Neuroscience (CCCN) is too heavy-going
for this introductory site. Details and full scientific bibliographies and references
in the 334 pp. Primal Eye book.
Without becoming embroiled in details of the neuroscience I would like to offer an
analogy explaining how the 'phantom eye' might interact with the substrate of neurons
and glial cells, connections, and electrochemical events that compose the brain.
Given that the brain is a kind of neuro-computer or connectionist machine, and that
patterns of electrochemical events represent the information that it is carrying
then the 'phantom eye' is a 'virtual computer screen' to which attention messages
are passed.
The "trick of nature" involves the fact that there is no longer a physical screen
(sense-organ) to which output is directed, and from which input is received. Pathways
to the expected device have been so established over evolutionary history that the
brain can reconstruct how this organ once acted, and internalise its functions. The
virtual screen decodes information conveyed by complex neuronal firings in much the
same way that a computer-monitor redraws electron impulses as patterns of coloured
pixels that are 'meaningful' to a viewer. Decisions concerning behaviour are then
based on this ‘meaningful' level of representation rather than low-level messages.
Behavioural choices previously determined by light information as it affected the
median eye are now taken by the computational brain and its abstract ‘sense appendage’....
no longer a slave to direct environmental impressions.
