The nexus between capitalism and religion appears to have shaped Amen's life. In Healing the Hardware of the Soul, his book about the connection between a healthy brain and the capacity for morality, conscience, and faith, Amen writes that he felt "led by God to pursue this [SPECT] work." These days, he uses his training and skills as a kind of reverse mission to churches, in an effort to persuade Christians and Jews that much "sinful" behavior may be due to brain problems, rather than evil motives. Some of his critics haven't looked kindly on this sense of religious mission. "He's a true believer, and evangelical medicine is scary," says Mayberg.

After medical school, Amen took a residency in psychiatry at Walter Reed Army Medical Center. In 1987, the Army sent him to Fort Irwin, California, as the chief psychiatrist--the only psychiatrist in the middle of the desert for thousands of soldiers and their families--a population rife with drug abuse, depression, anxiety, domestic violence, psychosomatic ailments, and stress. This new gig would have been a daunting job for any psychiatrist, let alone a young, newly minted, and relatively untried one.

Serendipitously, in the old World War II building that housed his office, he found an antiquated biofeedback machine (an instrument that measures physiological responses, via electrodes or sensors attached to various parts of the body) left by his predecessor. He found that, even as a novice, he could use the machine to train people to warm their own hands by using their imaginations--thinking about burying their hands in hot sand, for example. He could also use it to help them reduce their anxiety or relieve their migraine headaches, while gaining a sense of self-control and personal mastery. Enthusiastic about his new toy, Amen convinced his dubious commander to pay $30,000 for an up-to-date model and send him for 10 days' training in biofeedback.

The biofeedback training program in San Francisco was, Amen remembers, a revelation: "The best, most exciting, training I'd ever had. I was just stunned by what I learned." It was the first major introduction he'd yet had to the powerful interaction of brain, body, and mind, and he was hooked. He discovered that people could learn how to control their own autonomic nervous system--relax their muscles, calm their breathing, reduce their sweat-gland activity, lower their blood pressure and heart rate--to relieve both physical tension and mental anxiety. Moreover, through neurofeedback (a form of biofeedback in which electrodes are attached to the scalp), they could learn to change their own brain-wave patterns, and thus their mental states. "I was so excited to have this cool new technology that I went back to Fort Erwin and started using it on everybody."
