Regarding the quote "searching for new antidepressant drugs based on their ability to stimulate neurogenesis in the hippocampus. All antidepressants on the market demonstrate neurogenic properties in animals." Here's my problem: not all depression is equal. There are many different causes for depression (low blood sugar, infection, Graves disease, SADD, and of course reactions to prescription drugs) and consistently focusing not on the cause of depression but on manipulation and alteration of the hippocampus seems to me to be really bad science. A temporary "fix" is not a good answer to a really serious problem, because who then is going to take the time to discover the root cause of the depression?
