What can I say - Ray is right once again, which we knew from the start. In the words of the actual study - "serotonin is a downer". It appears SSRIs work by forcing the brain to achieve homeostasis, not by modulating serotonin levels. Again, Ray did say that as well - i.e. drug companies did not really know how their SSRI drugs work.

"...The low-serotonin theory is the basis for commonly prescribed anti-depressant medications called selective serotonin re-uptake inhibitors, or SSRIs, which keep the neurotransmitter's levels high by blocking its re-absorption into the cells that release it. Those serotonin-boosting medications actually make it harder for patients to recover, especially in the short term, says lead author Paul Andrews, an assistant professor of Psychology, Neuroscience & Behaviour at McMaster...When depressed patients on SSRI medication do show improvement, it appears that their brains are actually overcoming the effects of anti-depressant medications, rather than being assisted directly by them. Instead of helping, the medications appear to be interfering with the brain's own mechanisms of recovery."
"...The best available evidence appears to show that there is more serotonin being released and used during depressive episodes, not less, the authors say. The paper suggests that serotonin helps the brain adapt to depression by re-allocating its resources, giving more to conscious thought and less to areas such as growth, development, reproduction, immune function, and the stress response."
