      Chan, C.-C.; Scoggin, S.; Wang, D.; Cherry, S.; Dembo, T.; Greenberg, B.; Jin, E.J.; Kuey, C.; Lopez, A.; Mehta, S.Q.; Perkins, T.J.; Brankatschk, M.; Rothenfluh, A.; Buszczak, M.; Hiesinger P.R. (2011)
      Background: Neurons require highly specialized intracellular membrane trafficking, especially at synapses. Rab GTPases are considered master regulators of membrane trafficking in all cells, and only very few Rabs have known ...
    • 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 ...
    • Effects of stimulus range on color categorization 

      Wright, O. (John Benjamins Publishing Company, 2011)
      This chapter reports three experiments detailing the influences of stimulus range on color categorization. The results show that both categorization and speed of categorization of colorful stimuli can be influenced by ...
    • Category training affects colour discrimination but only in the right visual field 

      Drivonikou G.; Clifford A.; Franklin A.; Özgen E.; Davies I.R. L. (John Benjamins Publishing Company, 2011)
      There is indirect evidence that categorical colour perception (better discrimination of colours from different categories than those from the same category) can be learned. For instance, CP can be induced across a newly ...
    • Chromatic perceptual learning 

      Sowden, P. T.; Davies, I. R. L.; Notman, L. A.; Alexander, I.; Özgen, Emre (John Benjamins Publishing Company, 2011)
      Perceptual learning has been shown on a wide variety of achromatic visual tasks. However, very little work has explored the possibility of improvements on chromatically based tasks. Here, we used a transfer of learning ...

(Nature Publishing Group, 2011-05-15)
      The biological basis for regional and inter-species differences in cerebral cortical morphology is poorly understood. We focused on consanguineous Turkish families with a single affected member with complex bilateral ...
    • 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 ...

    • Neural correlates of acquired color category effects 

      Clifford, A.; Franklin, A.; Holmes, A.; Drivonikou V.G.; Özgen, E.; Davies I.R.L. (2012)
      Category training can induce category effects, whereby color discrimination of stimuli spanning a newly learned category boundary is enhanced relative to equivalently spaced stimuli from within the newly learned category ...
    • Growth hormone modulates hippocampal excitatory synaptic transmission and plasticity in old rats 

      Molina, D. P.; Ariwodola, O. J.; Linville, C.; Sonntag, W. E.; Weiner, J. L.; Brunso-Bechtold, J. K.; Adams, M. M. (2012)
      Alterations in the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptor (AMPA-R) and N-methyl-D-aspartate receptor (NMDA-R) have been documented in aged animals and may contribute to changes in hippocampal-dependent ...
    • Oscillatory synchronization model of attention to moving objects 

      Yilmaz, O. (Elsevier, 2012)
      The world is a dynamic environment hence it is important for the visual system to be able to deploy attention on moving objects and attentively track them. Psychophysical experiments indicate that processes of both attentional ...
    • Relative flattening between velvet and matte 3D shapes: Evidence for similar shape-from-shading computations 

      Wijntjes, M. W. A.; Doerschner, K.; Kucukoglu, G.; Pont, S. C. (Association for Research in Vision and Ophthalmology, 2012)
      Among other cues, the visual system uses shading to infer the 3D shape of objects. The shading pattern depends on the illumination and reflectance properties (BRDF). In this study, we compared 3D shape perception between ...

      Beliefs about personhood are understood to be a defining feature of individualism-collectivism (I-C), but they have been insufficiently explored, given the emphasis of research on values and self-construals. We propose the ...
    • Growth hormone and insulin-like growth factor-I alter hippocampal excitatory synaptic transmission in young and old rats 

      Molina, D. P.; Ariwodola, O. J.; Weiner, J. L.; Bechtold, J. K. B.; Adams, M. M. (Age Company, 2013)
