Study Reveals How Antidepressants Work… in rats, at least: “In a study conducted in rats, regular use of antidepressants

promoted the growth of new cells in the hippocampus, an area

of the brain where cells are known to waste away in people

who are depressed. The hippocampus plays a role in learning,

memory and mood.” It’s a well-kept secret, but we’ve been using medications to treat mood disorders for half a century or more, and we don’t know how they work. I’m not sure this study changes that.
