Does biology to do with depression?
Scientists have found differences in the brains of people who are depressed and those who did not.

A smaller hippocampus has fewer receptors for serotonin ( a neurotransmitter that gives us a sense of calm and contentment ). In a game that many other neurotransmitters such as dopamine or norepenefrin.
Although it is not yet clear why depressed people have a smaller hippocampus ( there are several theories ), one thing is clear - Depression is a complex disease that is affected by many factors, and the study of biological and chemical processes behind the state of depression will come to more effective ways to combat this disease.
