    • Attention modulates neuronal correlates of interhemispheric integration and global motion perception 

      Akin, B.; Ozdem, C.; Eroglu, S.; Keskin, D. T.; Fang, F.; Doerschner, Katja; Kersten, D.; Boyacı, Hüseyin (Association for Research in Vision and Ophthalmology Inc., 2014)
      In early retinotopic areas of the human visual system, information from the left and right visual hemifields (VHFs) is processed contralaterally in two hemispheres. Despite this segregation, we have the perceptual experience ...
    • Attention-dependent representation of a size illusion in human V1 

      Fang, F.; Boyacı, Hüseyin; Kersten, D.; Murray, S.O. (Cell Press, 2008)
      One of the most fundamental properties of human primary visual cortex (V1) is its retinotopic organization, which makes it an ideal candidate for encoding spatial properties, such as size, of objects. However, three-dimensional ...
    • Border ownership selectivity in human early visual cortex and its modulation by attention 

      Fang, F.; Boyacı, Hüseyin; Kersten, D. (Society for Neuroscience, 2009)
      Natural images are usually cluttered because objects occlude one another. A critical aspect of recognizing these visual objects is to identify the borders between image regions that belong to different objects. However, ...
    • Perceptual grouping-dependent lightness processing in human early visual cortex 

      Boyaci, H.; Fang, F.; Murray, S. O.; Kersten, D. (Association for Research in Vision and Ophthalmology, 2010)
      Lightness, the perceived relative achromatic reectance of a surface, depends strongly on the context within which the surface is viewed. Modest changes in the two-dimensional conguration or three-dimensional scene geometry ...
    • Rapid classification of specular and diffuse reflection from image velocities 

      Doerschner, K.; Kersten, D.; Schrater, P. R. (Elsevier BV, 2011-09)
      We propose a method for rapidly classifying surface reflectance directly from the output of spatiotemporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
    • Rapid classification of surface reflectance from image velocities 

      Doerschner, Katja; Kersten, D.; Schrater P. (Springer, Berlin, Heidelberg, 2009)
      We propose a method for rapidly classifying surface reflectance directly from the output of spatio-temporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
    • Visual adaptation to reflectance-specific image motion 

      Doerschner, Katja; Kam, T. E.; Kersten, D.; Fleming, R.; Seong-Whan, L. (Vision Sciences Society, 2012-05)
      Recently, we described several surface reflectance-specific motion characteristics that the visual system may use to determine whether a rotating object appears shiny or matte (Doerschner et al., 2011). We used an adaptation ...
    • Visual motion and the perception of surface material 

      Doerschner, K.; Fleming, R. W.; Yilmaz, O.; Schrater, P. R.; Hartung, B.; Kersten, D. (Cell Press, 2011)
      Many critical perceptual judgments, from telling whether fruit is ripe to determining whether the ground is slippery, involve estimating the material properties of surfaces. Very little is known about how the brain recognizes ...
