I am not making ANY claim that mRNA is the chemical of brain activities, nor that we are finite-state machines, et cetera ad nauseum. I am only trying to get us off of square zero in our characterization of how "being conscious" can be understood. It must be something which has a "window" of a finite time period, for we can sense the "motion" of experiences "through" our consciousness. It must be more involved than a ribosome or a basic Turing device, since in addition to being able to access the "present", it continually spins off things that we call "memories", and ties these things down into a place that allows them to be pulled back into the consciousness. (Actually, the recall of long term memory is more like the process of going into a dark room with a tuning fork, giving it a whack, then listening for something that resonates, going over to the sound, and picking it up ... so perhaps the memories are not "tied down" with pointers at all.) -------
