Same here !
After having read your above post over once, and having done some of my '
today's things to do list' items, I went over into my studio to check through some journals, files, and a book or two, to pull out some stuff to try to reword and explain to you. After some 90 minutes or so, I was kind of at a loss--
what to do??!. Wow...it's simply so much. I mean, William, we have to look at chromosome structure, protein function, DNA, mRNA, hormonal substances, cellular structure, function, and life patterns, prenatal neurocrest development, postnatal brain activities, brain structure and anatomy and function, and differences and similaritites between ganglion structures up to the brain build of the H. sapien, if we really want to get as full an understanding as possible to see just how it is a continuum (which it is, though not so absolutely smooth in shading differences).

I have noticed that you have tended (looking at that last post only, here) to express your opinion, or beliefs--
and that ability and 'art' (as I call it too) is well appreciated (Japanese students have problems with that ad nauseam (almost)). I'm still trying to see if I can come up with a way to make a decent presentation (but it might have to end up in another thread [which I am kind of working in]), but would like to point out one thing here. I can only ask for your concerned trust here, as I do make a good effort to stay up in the field, am subscribed to six journals, have availability to another four, continue updating my resource materials (the most recent being the two volume set
The Encyclopedia of Consciousness (Academic Press; 2009) which just came out in March), and make effort to be balancedly sceptic (as much as natural implicit conscious [sub/unaccessable conscious] will allow).
The human brain, just like the primate brain, just like the mouse brain, is made up of brain. This is like saying a muscle is made up of muscle--
in that the word can be a countable noun and an uncountable, collective noun. As far as brain (tissue; uncountable noun) goes, the substance and drive of activity between the mouse and the human is very, very small (especially if we allow that, for example the activation that substance A in the mouse brain executes equals that same execution as carried out by substance B in the human brain). Much of the structures of the human brain are found in the primate brain. What makes the big difference is size, prefrontal cortex, and system processing probably due to differences in environmentally induced needs that evolved simutaneously with the various splits in evolution. (For example brain size pressured social adaptations which in turned pruned certain traits selectively.)
The way memory works in a mouse brain is very much the exact way memory works in a human brain--
both are built of brain, you'll recall, so we shouldn't expect so much difference. Human genetic material can be added to mouse genetic material to make mouse models of human neurological diseases and malfunction, in order to study that of the human. Memory is divisible into a number of classifications, but short-term and long-term are two of the major divisions looked at. By removing brain area, we can completely destroy the ability to remember 90~95% of the daily life in long-term memory terms. What this shows, is that memory is brain, and is empirical a matter, as well. (Because if we destroy the ability to remember long-term (except for some implicit storage) we destroy the ability to learn from experience.)
For brain to store memory, in turn, certain genetic programming will have to be within a certain allowable build. Certain neuromodulators and transmitters will have to be within certain volume ranges. Also, the hippocampal formation will have to be relatively free from malformation, epileptic-like short circuits, and so on. This is the same for humans, mice, primates, and a number of other brains, on down the line, to lesser and lesser degrees. (We must keep in mind that even octopuses have been noted to learn from watching other octopuses act, and they have more of a ganglion structure than a brain structure.) We do have clues, major clues on how the brain uses memory to act (thus memory affecting brain).
Guilt, fear, and worry, come in maps, but the central player, and source of input, is the agmydala and the hippocampal structures (the amygdala being the main). These are midbrain structures which are found not only in humans, and which work alike across the brains that have them. A true smile, is not executed by the cognitive cortical area, but through this limbic system (the area based around those things just mentioned above). Forcing ourselves to smile, to think on certain things, acts on the reward circuitry, makes feedback loops, and leads to changes which alter, especially, the serotonin feed areas which lead to 'feeling better.' (also this can increase receptors for serotonin, thus creating a 'double shot' effect)
The number one function of the brain is to survive as a genetic built biological entity. The purpose of the body, is the extension and 'biosuit' for the brain. I would like to try to explain how your call for seeing a primate build a 'Kool-Aid' stand to believe that humans are in a line of contiuum with all animal forms, is likely sourced from an 'urban mythological' error. Then, explain some detail about sexual determination--
of course in both humans and non-human animals...to the extent that it is similar (some animals change sexes, you see, some are both [wouldn't it be easier if some 'boil built up on our bodies, bounced off like a Gremilin (the movie) then because our offspring?] This post is mostly embedding so as to demonstrate some points which in turn will demonstrate some points made towards the OP.
