The advent of functional neuroimaging techniques, including positron emission tomography (PET) and functional nuclear magnetic resonance imaging (fMRI), has opened up a new vista into the nature of brain functions underlying sensory and higher mental processes, including vision, visual imagery, creative planning and ideation. Recent functional imaging studies have fueled a new debate on the similarity or dissimilarity of the neuronal operations engaged by visual processes as opposed to visual imagery processes. On the basis of their experimental findings, some claim that visual perception and visual imagery occupy identical neuronal machineries in the human brain. Others, including the present author and his colleagues, claim that there is only a partial overlap between the neuronal populations engaged by sensory visual information processing and the generation and elaboration of visual imagery information in the human brain.
