Acupuncture and Modern Science

To the human body, acupuncture needles are a physical stimulus. In Western science, a stimulus is defined as a detectable change in either the external environment or within the body itself. When the body detects change, it produces a response. Although acupuncture is not yet fully understood by Western science, with modern technology scientists can now actually begin to "see" the body's response to acupuncture. For example, using an MRI (a very sophisticated x-ray), researchers have shown that when a needle is inserted at specific acupuncture points on the body, corresponding changes occur in the brain.
