comment Do feelings have a purpose?
For serotonin in particular, this paper: metabolism.math.duke.edu/docs/SSRIsJ7.pdf lists the average extra cellular and vesicular serotonin levels in normal and depressed patients. Depressed ones have ~75% less serotonin than normals. As such the "low oil" analogy still seems applicable to the serotonin case.

comment Do feelings have a purpose?
The way I was thinking about the two questions you pointed out is: a car has an engine oil indicator that lights up if the engine oil is affected (low?). If neurotransmitters are the equivalent of oil in a human brain, then maybe changes in their levels activate feelings to signal the change. I have no way to prove this, and was hoping someone would comment on whether or not there's any truth to the analogy.

comment How does one study the effect of a dietary supplement on cognition?
I found this article that outlines studies dealing with vinpocentine, it has more detail than Wikipedia: priory.com/focus15.htm

Amazing answer! I especially appreciate you putting the 4 points to test and specific keywords, like allosteric modulator.

comment Does anxiety produce adrenaline or does adrenaline make the person anxious?
Check out this article on anxiety: newsmaxhealth.com/dr_blaylock/Anxiety_Brain_Function/2011/04/21/… The article mentions stress and inflammation , but there is not a word about adrenaline. Maybe you were thinking of being startled or fight/flight?

comment Can we stop the brain from processing a particular task?
I like the idea of observing one's cognitive processes.

@Gasan Exactly! This is why I quit playing that game the very next day. I was concerned that I may lose more sleep in the future.

comment Is there a “foreplay” equivalent, priming activity for thinking or conversation?
Cognitive state alignment is a really good term for what's being discussed! I'm more interested in the second scenario - what activities can help one person change the cognitive state of another(or one's own).

Checked depersonalization, it sounds a lot like the typical experience of a dreamer within a dream.

comment Is there a “foreplay” equivalent, priming activity for thinking or conversation?
I guess this question is about this analog nature of flowing in and out of different states of mind. Not discrete ones, but different. In the foreplay, it's fairly easy to measure arousal, especially if male :) . Baseline is replaced by arousal. I don't really know what is the baseline change for thinking or conversation. What is this disinhibition?

comment Can we stop the brain from processing a particular task?
A while back I played a game called diplomacy, which is very complex strategically. When I went to sleep that night, thinking about the upcoming turn, my brain was going through all possible combinations of turns and outcomes. One by one. For about 3 hours as I could not fall asleep because of this. While I did find the correct solution, it was quite unpleasant , non normal sleep. Maybe this is the kind of unpleasantness that the author refers to

This begs the question of what is the cognitive equivalent of ice that is being broken. What is this inhibition that prevents easy social interaction in a group

Good point about making money without scientific backing. I"m looking at this search result for (Vinpocetine metabolic rate -calories) smart-drugs.net/info-vinpocetine.htm The claims make it seem like a super drug, but it doesn't say how long it works, how quick the onset is, if it has to be taken extended period of time and what the benefit %increase is. It would be great to see a study that deals with the points above.
