Sorry for not putting in more detail. I mean looking at brain glucose usage,
brain level activation by brain oxygen use, and producing "Medical Imaging of
Brain Activity". Like the heart, the brain is different from other organs in
many ways. And studying "activation" by the aforementioned methods will give
you a good idea of some of what is going on emotionally. Especially regarding
the common emotions. So you can get a good idea that someone is worried, or
aroused or anxious, as opposed to relaxed or calm etc.
In regard to humans this has grown as techniques for studying the brain, has
grown as techniques have become less invasive. So lone can kind of get general
states out of things, but the specifics are hard to come by. It is sort of like
a Thermal IR. image can tell you pretty clearly if someone is sexually aroused,
but you have to pretty much still ask them why they are aroused, and what turns
them on.
This is another set of stuff I will have to dig out of my archives, the forces
of whatever permitting. Things have somewhat gone beyond R/L dominance, to
noticing what happens when both R and L pieces are turned on. Music seems to do
this. Almost any type of music.
Of course you are right, much of this is doubtful, and since the chance it is
truly random sampled with a large enough sample hasn't overall been done yet.
So all of this stuff is intriguing with lots of guess work and informed (not
uninformed) speculation going on.
Have Fun,
Sends Steve
