Objective: To propose and describe two distinct cerebral systems for the imaginalrepresentation of the same object—the lion—differentiating a visual-perceptive imagefrom a symbolic-affective oneiric image.Methods: Integrative theoretical review based on functional neuroimaging, reports ofcortical stimulation, sleep studies, phenomenology of perception, and psychiatricclinical observations.Results: Evidence suggests the existence of a visual system (occipital and inferiortemporal cortex) responsible for clear, perceptive images, and an anterior limbic-temporal system that generates symbolic, embodied, and affective images, even in theabsence of primary visual activity, such as in deep sleep.Conclusion: The human brain represents the same object through two complementaryneural pathways: one objective, optical, attentional; the other subjective, affective, andsymbolic. This distinction has clinical and theoretical implications for psychiatry,neuroimaging, psychopathology of dreams, and the phenomenology of consciousness.Keywords: Temporal cortex; Imagination; Neuroimaging; Representation; REM sleep.
