Boy, thanks for jogging my memory. KK is sweet to say I'm intelligent but my memory is terrible for everyday stuff. When my adrafinil kicks in again, it'll be better.
Yes, I read over the articles. Basically, what was being said is that serotonin has far-reaching effects in proper brain formation & function.
During fetal & early post-natal brain formation, serotonin plays a major role in the development of a normal & healthy anxiety or stress response. Without it, the brain wouldn't develop any stress response (or anxiety) but an excess during early brain development, post-natally, can leave such an individual overly sensitive to excess anxiety (at least in mice but most likely in humans too).
It goes on to explain how scientists were able to test these ideas by knocking out a specific gene in mice that controlled serotonin response in cells of the mice's developing brains to be able to compare them to mice who developed normally.
All the new research was pretty interesting but of no relevant value to those now suffering from anxiety. At this point of time, anxiolytic (antianxiety) drugs are the only means of controlling it. The scientists involved hope to make use of their studies in future methods of understanding anxiety better. Sorry I can't give you something more positive & concrete. The point of the article was to show how much more a role neurotransmitters can have in development than previously thought.
