| Summary, etc. | RésuméL’agnosie visuelle est un trouble de reconnaissance, se limitant à la seule modalité perceptive visuelle, et ne pouvant s’expliquer par un déficit perceptif élémentaire ou un autre déficit cognitif. On distingue classiquement l’agnosie aperceptive de l’agnosie associative. L’observation d’agnosies sélectives d’une seule catégorie d’objet (prosopagnosie pour les visages ou alexie pure pour les mots) pourrait suggérer l’existence de deux mécanismes différents : le premier analytique nécessitant de considérer chacun des constituants du stimulus cible et leurs relations entre eux (qui serait prépondérant dans le processus de lecture) et le second configural consistant en une concordance du stimulus cible et d’une représentation interne (qui serait prépondérant dans l’analyse des visages). Les études neuropsychologiques, anatomiques et d’IRM fonctionnelle ont permis de souligner le rôle critique de certaines régions cérébrales, ce qu’illustre parfaitement la prosopagnosie, avec l’identification de la fusiform face area (FFA) et de l’ occipital face area (OFA), et l’élaboration de modèles explicatifs de la reconnaissance des visages. |

| Summary, etc. | Prosopagnosia and other visual agnosiasVisual agnosia is a deficit in object recognition confined to a selective perceptual modality, i.e. visual modality, and which is not due to an impairment of elementary visual processes or another cognitive deficit (language or memory for example). There are usually two different categories: apperceptive visual agnosia is characterized by an incorrect percept of the stimulus, and associative visual agnosia is the result of the inability to assign meaning to what is (correctly) perceived. Impaired recognition of visual stimuli within a single category, e.g. prosopagnosia (for faces) or pure alexia (for words), may suggest two different mechanisms. The first one is analytic, considering each of the parts of the stimulus and their spatial relationships. This analytic mechanism would be dominant for reading. The second one is configural, associating the stimulus with an internal representation. This configural mechanism would be dominant for the faces analysis. The study of brain-damaged patients and normal subjects, especially with neuropsychological assessment, anatomical and functional brain imaging, remains essential to demonstrate causal links between brain structures and cognitive functions. Prosopagnosia perfectly illustrates this point, with the identification of properties of the “fusiform face area” (FFA) and the “occipital face area” (OFA), leading to the development of explanatory models of face recognition. |
