Журнальный клуб 11.10.2012

11 октября в 15:00 в конференц-зале ИВНД и НФ состоится заседание Журнального клуба. Доклад подготовит Сергей Калинин на основе статьи: A Real-World Size Organization of Object Responses in Occipitotemporal Cortex, Neuron 74, 1114–1124, June 21, 2012

While there are selective regions of occipitotemporal cortex that respond to faces, letters, and bodies, the large-scale neural organization of most object categories remains unknown. Here, we find that object representations can be differentiated along the ventral temporal cortex by their real-world size. In a functional neuroimaging experiment, observers were shown pictures of big and small real-world objects (e.g., table, bathtub; paperclip, cup), presented at the same retinal size. We observed a consistent medial-to-lateral organization of big and small object preferences in the ventral temporal cortex, mirrored along the lateral surface. Regions in the lateral-occipital, inferotemporal, and parahippocampal cortices showed strong peaks of differential real-world size selectivity and maintained these preferences over changes in retinal size and in mental imagery. These data demonstrate that the real-world size of objects can provide insight into the spatial topography of object representation.
