우반구와 좌반구의 기능적 비대칭성

Abstract

Asymmetry between right and left hemispheres had been of interest long before Broca reported the specialization of the left hemisphere for language. Recently, however, the concept of left hemisphere dominance was changed into an effort to investigate functional differences between two hemispheres as neuroscientific research has extended into the areas of visuospatial perception, emotion, and social cognition. Here, we review the diverse literature describing hemisphere asymmetries in terms of evolutionary theory, neuroscience, and psychotherapy. First, the conflict between both hemispheres, from ancient times until the present, ending in the final triumph of the left hemisphere, will be discussed. Then, from the neuroscientific perspective, the functional asymmetries between right and left will be provided. Finally, the application of functional asymmetry between two hemispheres to psychotherapy will be addressed through right-brain affect regulation and couple cases. From the perspective of neurobiology, psychotherapy can stimulate horizontal, and interpersonal integration.
