Abstract

The present study examined the coding of retinal eccentricity spatial position in object selective cortex. Using a wide-view (about 120°) visual presentation system developed for vision research and functional magnetic resonance imaging (fMRI), the subject were presented with object, which were presented at a range of viewpoints in 6 level of eccentricity degree. We investigated the BLOD response to stimuli in two regions in the ventral visual cortex (V1) and Lateral Occipital Complex (LOC). The analysis further revealed the weaker BLOD response in the bigger eccentricity in both V1 and LOC areas. However, the activation to objects were quiet different in the cortex region. The V1 areas had flatter decreasing response as eccentricity increasing. However, V1 had bigger response in 11°eccentricity. And the LOC areas had neural activities decreasing sharply as eccentricity increasing. The result suggests reflected the neural response character influenced by eccentricity and stimuli cartage.
