Actually if you read my blurb you'll realize I'm only describe the functionality that the world puts on auditory processing in the brain. Although much is known of how speech is processed we don't know whether the phonemic processing the brain produces gives us those chunks we obviously use actually produces words, sentences, etc. We do know how words are broken up by processing frequency sweeps and on-off markers and we do know there are important roles played by high and low frequency signals within speech.
As I said it is motor articulation that provides images of speech we to which we have access for experience, just as spatial and frequency arrays provide us with scene material we report as experience, So at a gross level we know such are formed and made as outputs through muscle and neural activity groupings.
We also have a lot to say about somnolence, arousal, attending, and awareness processing structure and function, We also know of many association players, enough so that we can read whether one is deciding or has decided and to some extent we can know what they decide and how they are going to articulate or respond.
Much of our squirt drivers are well known, but even with some very fine grain understanding we have not been able to predict by such behavior what one is going to do, only whether one is ready or primed for use of known data.
It is stuff like this that I find advancing very rapidly, actually to the point we can build successful behavioral simulations based on the data at hand.
I've already pointed out some obvious players in is the information we access for experience such as ascending, descending neural communication and narrow and broad associative neural processing.
We know there are at least three clockable sets of chemical mechanics within individual neurons and neuron groups.
As early as the turn of the nineteenth century we have found and used indicators of neural information integration and response preparation. This knowledge is so streong that we can build very valid and reloable simulations of processing and task performance. In the seventies we broke through in speech recognition and production. True the best models are still numerical models but there are pretty good analytic models coming out now to conduct both speech recognition and speech production.
The same can be said for ambulatory and visual models.
It seems to me that clinical difficulties in using this information is one of cost rather than one of knowledge. There are solutions in aerospace and robotics that can be applied if there is enough interest to spend the money. But, as we all can see there is a lot of resistance to providing sufficient funding for such endeavors for other than the very famous or the extremely wealthy.
Apparently we care enough to save lives, but don't care enough to make the saved functional again.
Again, my 'explaining' is only in the information output the brain produces that is coherent and not in why this is so a=or how it is accessible as if there were an internal viewer. We know that which produces empathy is involved and we know we have many areas of the brain innervated with what has come to be known as mirror neurons. We know there are both ascending and cross modality arousing substrates and many believe the cross modality substrate is involved in experiencing.
If you read about
locus coeruleus you're sure to get a whiff of how conscious is mediated.
OK a lot of words. Not much about a place or brain aspect defining consciousness beyond what we know. Yes, a lot about information processing, motor control, arousal and awareness neurophysiology and neurochemistry and maybe a faint scent of what is involved in consciousness mechanics.
As for seeing a tree that's simple. That's visual and language processing articulated either via scene or vocalization mechanics or both. The brain is producing the experience and telling you through output mechanics what is it's content. Try viewing a pure visual situation with no requirement for acoustic participation. You'll find there is no tension in your throat. Yet if the scene has writing or a sound in it there will be that throat tension, maybe even to the extent of an experience of speaking.
Yeah, way more than necessary.
