There is alot of new research on serotonin in the brain too:
The serotonin transporter gene is inherited and has 3 forms.
This very interesting article explains it and some other psychology involving inheritance/behavior and disorders:

95% of the serotonin you have is in the body (not the brain).
In fact SSRI drugs can cause diarrhea and nausea in some people because of this.
The drug cisapride (Propulsid) was the first GI serotonin receptor agonist. Unfortunately it had drug interactions with some drugs and with low electrolyte status it could cause heart arrhythmias. But it was highly useful for gastroparesis and some IBS patients, and GERD. Because doctors failed to follow guidelines sent to them via warning letter, and continued to misuse this drug, the FDA took it off the market in US.
