The Upward Spiral

“You can't control what you see, but you can control what you're looking for.”

Good book for a basic explanation of how depressive, negative thoughts and behaviors interact to start the downward spiral into depression. The bulk of the book retells the various studies and experimental results in neuroscience that explain how depression might work, in a more accessible way for the general reader. If this is the first book you've picked up on neuroscience/depression, it's a good introduction.
