Toward integrating psyche and soma: psychoanalysis and neurobiology

The brain is the "key organ" for understanding mind/body/illness relationships. During the past two decades neurobiological research has generated a plethora of new data and concepts which have increased tremendously our knowledge of the functioning brain. As a result the psychoanalytic view of the relationship between mind and brain may seem at risk of becoming outmoded. Yet while psychoanalytic theory may no longer be wholly tenable, psychoanalysis continues to offer interesting and heuristically valuable isomorphic models of cortical function. On the other hand neurobiology provides a corrective influence on psychoanalytic concept-building, causing theory to be refined as it is tested against the results of research. One possible result of interdisciplinary cross-fertilization is that a revised theory of the function of dreams and fantasy may throw light on the vicissitudes of somatic experience, and the pathogenesis of psychophysiological disorder.
