Pain is an inevitable part of existence, but severe debilitating or chronic pain is a pathological condition that diminishes the quality of life. The Brain and Pain explores the present and future of pain management, providing a comprehensive understanding based on the latest discoveries from many branches of neuroscience. Richard Ambron—the former director of a neuroscience lab that conducted leading research in this field—explains the science of how and why we feel pain. He describes how the nervous system and brain process information that leads to the experience of pain, detailing the cellular and molecular functions that are responsible for the initial perceptions of an injury. He discusses how pharmacological agents such as opiates affect the duration and intensity of pain. Ambron examines new evidence showing that discrete circuits in the brain modulate the experience of pain in response to a placebo, fear, anxiety, belief, or other circumstances, as well as how pain can be
