Future perspectives for applied psychophysiology and biofeedback.

Current circumstances in both the health science and health care delivery systems in our country have created serious problems for health professionals, particularly for those of us in the relatively young field of biofeedback. At the same time, recent and emerging developments in the neurosciences and in technologies for biological measurement offer exciting new opportunities for the applied psychophysiology upon which our field is based. Examples of these developments include the elucidation of potential neurophysiological mechanisms that may mediate the psychophysiology of immune system responses, and technical achievements leading to on-line, noninvasive magnetic resonance imaging of brain neurochemistry. The issue of perspective is raised in relation to our response to both the challenge and the opportunities of our times.
