Since the publication of Whitman's prescient poem “I Sing the Body Electric” in his collection Leaves of Grass, the electrical nature of brain and body has been confirmed by an abundance of scientific research. Seemingly much of what goes wrong with the brain could hypothetically benefit from finely calibrated pulses of electricity. The most promising available neuromodulatory technique is deep brain stimulation (DBS), which has shown clinical efficacy and safety in helping to improve certain brain-related problems such as movement disorders.1 The improvement in the symptoms of many patients has captured the attention of the general public, and neuroscientists are now introducing DBS for treatment of psychiatric disorders such as depression and obsessive-compulsive disorders.
