Neurosciences Research Institute, Aston University, Birmingham B4 7ET, UK

Department of Psychology, Northwestern University, 2029 Sheridan Rd, Evanston, IL 60208, USA
Vision Res 41:3883-902. 2001..It is thus suggested that the rapidly adapting contour orientation aftereffects reported here may be mediated by high-level neural units that encode global configurations of orientation (e.g. convexity and concavity)... - Backscroll illusion: apparent motion in the background of locomotive objectsKiyoshi Fujimoto
Intelligent Modeling Laboratory, University of Tokyo, 1 1 1 Yayoi, Bunkyo ku, Tokyo 113 8657, Japan
Vision Res 46:14-25. 2006..This result led us to hypothesize that the backscroll illusion is generalized to objects that have shapes implying their moving directions... - Reversal of apparent rotation in the Enigma-figure with and without motion adaptation and the effect of T-junctionsSimone Gori
Brain Research Unit, Department of Neurology, University Hospital, Breisacher Str 64, 79106 Freiburg, Germany
Vision Res 46:3267-73. 2006..This suggests that T-junctions formed by the radial rays impinging onto the colored rings of the Enigma figure are instrumental for eliciting the rotary motion and may rule out a low-level sensory origin of the illusion... - Contingent aftereffects distinguish conscious and preconscious color processingEdward Vul
Department of Psychology, University of California San Diego, La Jolla, California 92092 0109, USA
Nat Neurosci 9:873-4. 2006..The more restricted frequency response of the conscious perception of color suggests that extra integrative steps give conscious color perception a time course substantially slower than that of early cortical mechanisms... - Changes in stereoscopic depth perception caused by decentration of spectacle lensesJ R Jimenez
Departamento de Optica, Universidad de Granada, Spain
Optom Vis Sci 77:421-7. 2000..A decreased disparity range has also been confirmed with figural-stimuli stereograms and using prisms for generating the prismatic effects... - Cortical dynamics of lateral inhibition: visual persistence and ISIG Francis
