Fantastic explanation of how serotonin works -- in English. Depression happens, sometimes, because serotonin malfunctions as messages travel through neurotransmitters from sending brain cell to receiving brain cell. The Serotonin inhibitors, like Zoloft, stop the chemical from being absorbed into the receiving cell too quickly. Depressed people have to control their brain network manually. Understanding how it works is key to not blaming oneself emotionally for having the disease.
