A method for agent dissemination using a neural conduit. In one embodiment, agent dissemination is facilitated, for example, by the application of thermal energy, ultrasound energy, radiant energy, electromagnetic energy, or electrical current. As one example, agent may be provided to a sensory organ such as the eye for dissemination along the optic nerve to the central nervous system. As another example, agent may be provided at an acupuncture site for dissemination along a peripheral nerve to either a second peripheral nerve site or a central nervous system site.
