Alex Korb, a postdoctoral researcher at the Semel Institute for Neuroscience and Human Behavior at UCLA, has published the book, The Upward Spiral: Using Neuroscience to Reverse the Course of Depression, One Small Change at a Time (New Harbinger Publications).

One of Amazon's bestselling books on the subject of depression, the book explores the brain's role in mood, habits, decision-making and motivation, and presents new advances in neuroscience that have uncovered dozens of small life changes that individuals can make on their own to modify the brain circuits and neurotransmitter systems involved in depression, a condition from which more than 15 million Americans suffer at any given time.

Korb earned a B.S. in neuroscience from Brown University in 2002, and a Ph.D. in neuroscience from UCLA in 2010. He wrote his dissertation on depression, and he has published numerous scientific articles on the subject. His postdoctoral research focuses on developing therapeutic-focused ultrasound neuromodulation for treatment of mental and neurological disorders. He has additional research interests in using measurements of brain activity in depressed patients to predict antidepressant treatment response. 

Korb also publishes the popular blog PreFrontal Nudity for Psychology Today, in which he explores "how the tendencies of your brain can both ruin and enrich your life."
