Just encountered this on http://www.sciencedirect.com/science/ar ... 8914000305 - but it makes little sense rationally, along with impulsivity if there is a low level (which is also linked to increased catecholamines, which would make more sense). It makes little sense because psychedelics usually lead to the calmest state...

A lot of what was published there was also based on material from several years ago which was also probably based on previous material in Drugs & Alcohol 101 from even several more years ago before that where they always had this habit of linking serotonin to everything.

You are probably right that they are flawed in their conclusions, for example, many of the members of the psychiatric-community believed that a serotonin-deficiency was responsible for depression, due to erroneous so-called "science" within the main-stream, and many of them still probably believe that, because, well, let me just quote something...

Alright, with that having been quoted, one of the beliefs about depression continues to remain that it is due to a serotonin-deficiency, despite existing evidence to the contrary. The logical-fallacy is that the studies were done in such a manner as to put skin-cream on a rash, and if the rash went away, then the Non-Sequitur was basically that rashes on the skin were caused by a Skin-Cream Deficiency. More on that here...

Also, for the record, a LOT of information I read within so-called "medical" literature OFTEN tends to be the EXACT OPPOSITE of reality, and there actually are reasons for violent-behaviour, but has more to do with problems in bio-electro-magnetic channels of energy-flow, than it does to do with anything that is purely bio-chemical. Another known cause of violence are withdrawal-symptoms to various drugs or other such addictive-substances. Once you understand how "mind" can be affected/altered/manipulated, even though the "mind" remains very mis-understood in Western-cultures (such that they mistakenly equate IT and the brain to being exactly the same), you get a much better idea of how and why certain behaviours are likely to result under certain conditions.

It would be quite a surprise if you realized how little we actually know.

Linking serotonin levels to anything externally observed can be fraught with bad causality unless the methodology is really sound *and* it's built on a broad base of supporting knowledge about the processes involved. Rarely are simple, direct correlations to serotonin alone accurate.

Serotonin was our (animals) first neurotransmitter. As such it is involved in regulating everything from sleep to digestion to thirst to immune/autoimmune and about a dozen other processes that need to be dynamically maintained or kept in balance. In humans and other such animals it also helps regulate mood, perception, etc.. But it doesn't directly regulate any of them; instead it often co-regulates them along with a more task-specific hormone or neurotransmitter, sometimes many. And in most cases, the process being regulated and the other hormone/neurotransmitter in turn regulates serotonin in a two, three or even four way feedback/hysteresis (hate that word) mechanism.
