Book excerpt: Ce travail porte sur l'approche neuropsychologique des substrats neuronaux de la perception visuelle des actions. La première partie est consacrée à une revue des connaissances actuelles sur le système visuel, en particulier de ceux issus de la neurophysiologie. Ces travaux soulignent l'existence d'une ségrégation anatomique et fonctionnelle entre deux voies corticales visuelles, la voie ventrale, formée des cortex occipito-temporaux internes, impliquée essentiellement dans la reconnaissance visuelle des objets (" what ") et la voie dorsale, constituée de cortex occipito-temporaux externes et de cortex occipito-pariétaux, et dont la fonction serait dévolue aux traitements spatiaux et visuo-moteurs (" where " et " how "). Nous nous sommes interrogés sur les contributions respectives de ces deux voies dans la perception, l'identification et le maintien de représentations d'actions présentées visuellement. La première expérience est consacrée à l'étude des capacités de discrimination visuelle de deux actions de locomotion humaine - marcher et courir - présentées sous la forme de pattern de points (" biological motion ") sous des angles de vue canoniques et non canoniques. Les sujets sains sont capables de discriminer ces deux actions, même quand certains indices de forme (détérioration de la symétrie des membres) sont escamotés. La présence de mouvement permet aux sujets d'organiser de manière cohérente la perception de ces patterns de points complexes en actions finalisées de locomotion humaine. La suppression du mouvement rend l'interprétation de ces patterns difficile mais n'abolit pas les capacités de discrimination visuelle de ces actions, ce qui implique que ces patterns contiennent des informations " suggestives " de mouvement. Nous avons ensuite étudié les performances de deux patients cérébro-lésés JR et AK dans des tâches de détection de cibles statiques, de discrimination de direction de cibles en mouvement linéaire et de mouvement cohérent, ainsi que dans des tâches d'identification d'objets animés et de " biological motion ". Une double dissociation concernant l'identification de formes et la perception visuelle du mouvement est retrouvée entre JR, qui présente une agnosie visuelle aperceptive secondaire à des lésions étendues des régions occipito-temporales et AK qui présente une akinétopsie en relation avec des lésions dorsales. Par contre nos résultats suggèrent que l'intégrité des deux voies visuelles - ventrale et dorsale - est nécessaire à la reconnaissance de stimuli combinant des informations de formes et de mouvement. La troisième section expérimentale concerne l'étude des performances de sujets sains, de celles de JR et de X, patient affecté d'une pathologie (dégénérescence cortico-basale) affectant les praxies, dans une tâche d'identification de photographies de gestes transitifs. Ces résultats montrent que chez le sujet sain et chez JR, la forme du geste prend le pas sur l'identité de l'objet, alors que le contraire est retrouvé chez X. La dernière partie est consacrée à l'étude de l'imagerie visuelle de JR. Nos données retrouvent une préservation relative de l'imagerie visuelle de JR pour le mouvement, et sont en accord avec la conception selon laquelle il existe un substrat neuronal commun pour la perception visuelle et l'imagerie mentale

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude a porté sur la neuropsychologie et la neuro-imagerie fonctionnelle d'un cas exceptionnel d'agnosie visuelle (SB) acquise dans l'enfance. Les lésions ont touché la voie ventrale (VV) bilatéralement, et la voie dorsale (VD) à droite. Les tests visuels ont montré que SB utilise une stratégie de reconnaissance visuelle au "trait par trait", et semble avoir préservé un module de traitement implicite des visages. Une expérience de détection de formes en IRM a montré que SB utilise des stratégies visuelles impliquant la VD gauche pouvant pallier une quasi-abence de la VV. Ces observations nous ont montré la nécessité de prolonger l'étude du "rôle" des voies ventrale et dorsale dans la perception visuelle. Enfin, une étude en neuro-imagerie sur la perception visuelle résiduelle du mouvement chez des hémianopsiques a montré que l'activité des aires occipitales latérales, mais pas celle du cortex clcarin, est nécessaire pour la discrimination du mouvement chez ces patients.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1987, this book, attempted to bring together work by researchers concerned with the functional and neurological mechanisms underlying visual object processing, and the ways in which such mechanisms can be neurologically impaired. The editors termed it a 'Cognitive Neuropsychological' approach, because they believed it tried to relate evidence from neurological impairments of visual object processing to models of normal performance in a new and important way. Two broad aims are apparent. One is to test models of normal performance by evaluating how well the models account for the patterns of impairment and preservation of abilities that can occur following brain damage. The other is to use models of normal performance to further their understanding of acquired disorders of visual object processing. These aims distinguish the approach from neuropsychological work whose primary aim is to relate acquired deficits to the sites of damage, and from work in the field of cognitive psychology which attempts only to develop models of normal performance. chology which attempts only to develop models of normal performance.
Download or read book Body MRI Cases written by William E. Brant and published by Oxford University Press. This book was released on 2013-02-19 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Body MRI: Cases in Radiology serves as a ready reference of 141 cases and nearly 900 superb quality images of common and uncommon conditions encountered in the daily practice of body MRI. The book is specifically intended for radiology residents and fellows as a study guide to broaden clinical knowledge and improve diagnostic skills when reviewing MR images of the liver, biliary system, pancreas, urinary tract, adrenal glands, peritoneal cavity, spleen, gastrointestinal system, female genital tract, vascular system, and heart. The selected cases provide outstanding examples of various disease states and their appearances as demonstrated by MR imaging using a variety of pulse sequences. Each case is shown on the front page with a brief clinical history and multiple, carefully selected images that best show the important findings. When turning the page, the imaging findings, differential diagnosis and important teaching points are given in bullet-point format facilitating the learning process and allowing the reader to improve interpretation and diagnostic capability in body MRI. Cases are presented in random order to mimic the diagnostic challenges that typically occur when reading the daily worklist of cases in a routine clinical body MRI practice. Readers can also review the cases by organ system through the Index of Cases found in the back of the book. Body MRI Cases is also an excellent companion study guide to Essentials of Body MRI by the same authors. Together, these texts provide an excellent foundation in Body MRI.
