It occurs to me that a good fraction of brain function is focused on absorbing sensory information and instantly processing it.
Given the amount of information that we process the brain is a remarkably quick analog computer. Not only does it process all that incoming information on the fly, it also does a large fraction of decision making on the fly. There is virtually no lag between incoming signals and outgoing decisions (e.g. move that leg, scream at cabbie, etc).
But there is a more complex and much slower digital part of our brain that does post-processing. We call this ‘thinking’. In this case we take in all the information and do off-line and much slower processing in order to do decision making.
It does not surprise to me that the best off-line processing is done during sleep hours. There must be parts of the digital brain that multi-task and when we are asleep these parts of the brain can be dedicated to the post-processing tasks at hand.
What we call intuition, id or gut-feel is the instant, analog decision making processes. These must be rules- and pattern- based; essentially we have in the analog parts of our brains great big decision-making flow charts that allow us to make instant decisions for certain scenarios. These flowcharts must be HUGE.
And then we must have a function, the ego, that checks the integrity of the use of these flowcharts and that automatically flick-passes a decision-making process across to the digital side of the brain, the super ego, if the set of external conditions does not match the flow chart conditions closely enough (which would result in errors in decision making).
Its the highly evolved digital part of our brain that differentiates us from the lower animals that probably are almost entirely analog.
Education seems to be all about exercising and training the digital processing part of our brain. Without education it seems that many people simply can’t be trusted to use this part of their brain to make decisions.
I wonder if we inherit the flowcharts? I guess we must. Which means that DNA must also be a memory technology. I wonder how many gigs we get?
I also wonder if we can transfer proven digital processes across to our own analog flowcharts. I bet we can, through practice. But do we pass these onto our kids? I bet we do – that is, we get to add content to all of our descendants. Hence our need to mix up the gene pool; to spread the new flowchart components.
‘Living in the moment’ means shutting down the digital thinking part of your brain and living instinctively. Whereas meditation additionally tries to slow down the sensory input hence slowing down the analog flowchart side of your brain.
