Abstract: | This paper presents a review of the empirical evidence bearing on the localization of the image-generation process in cerebral structures and examines several issues related to the study of functional hemispheric asymmetry. In spite of recent claims that the left hemisphere is specialized for the generation of mental visual images, an examination of the relevant data and experimental procedures provides little support for this view and suggests that both hemispheres simultaneously and conjointly contribute to this process. Methodological and theoretical issues related to the localization of functions in the brain, some assumptions guiding laterality research, and computational models of cerebral lateralization are briefly discussed. |
