Over the past several years, the pace of research on the control of axonal growth has increased at a remarkable rate, and this activity is reflected in a growing literature dealing with various aspects of axonal growth and regener­ ation. It appears timely to review the role played by axonal transport in the intrinsic responses of neurons in the growth and regrowth processes. Through the cooperation of the senior editors of this series, we have been given the opportunity to bring such a focus to the current volume. We wish to acknowledge that the contributing authors attended a confer­ ence on "The Role of Axonal Transport in Neuronal Growth and Regeneration" held in Tallahassee, Florida in March, 1983, sponsored by the Psycho­ biology Research Center of the Florida State University. It is our hope that many of the perceptions and insights expressed in these chapters resulted from our interactions.
