A Basis of Consciousness
(Copyright 2003, James
Michael Howard,
I define "consciousness" as one
brain mechanism having to inhibit or enhance another. This makes one mechanism
"aware" of the other. Now this may be magnified into any level of
complexity of "on off" mechanisms monitored by other "on
off" mechanisms. This is a form of "consciousness."
However, I suggest the real key to
"consciousness" is awareness of "need." When the above
scenario is connected with a mechanism which generates "need," the
interaction reaches the level of self awareness. Hence, hunger, thirst, etc.
and sex produce "self awareness" in their satisfaction or deferral.
(The memories of how these needs were met are stored in the association areas
which refine the opportunity for satisfaction and increase awareness. I suggest “consciousness” cannot exist
without memory.)
The third part is "drive."
"Need" generates drive. This is the area which machines, at least at
this time, may not be able to mimic. A machine that must seek and find energy,
for example, is simply using "on off" mechanisms. I suggest the
"drive" of animals results from the
characteristic of nerves which differentiates them from other tissues. I think
our drive comes from the "addiction" mechanism. That is, our nerves
evolved the ability to increase receptors in response to the stimulus of
entering molecules which trigger the addiction mechanism. Therefore, an
accumulation of nerves, the brain, becomes a site which is constantly
increasing its "need" for various molecules by constantly increasing
receptors for these molecules. This is the basis of our drive mechanism.
I suggest "consciousness" consists
of these mechanisms: control of one mechanism over another, especially
involving mechanisms that are identified as "needs," and the
addiction mechanism which constantly renews "needs."
