- Anisotropy for direction discrimination in a two-frame apparent motion displayY Ohtani
Laboratory of Psychology, Institute of Technology, Matsugasaki, Japan
Vision Res 37:765-7. 1997..Human motion vision is anisotropic in the lower half of the visual field...
- Motion assimilation for expansion/contraction and rotation and its spatial propertiesY Ohtani
Laboratory of Psychology, Faculty of Engineering and Design, Kyoto Institute of Technology, Japan
Vision Res 38:429-38. 1998..The results were discussed in terms of the interaction between local motion detectors and higher-order detectors which monitor global motion of the whole stimulus pattern...
- Magnetic responses of human visual cortex to illusory contoursYoshio Ohtani

- Spatial-frequency uncertainty and cuing effects on psychometric functions for contrast detectionYoshio Ohtani
Faculty of Engineering and Design, Kyoto Institute of Technology, Japan
Psychon Bull Rev 9:270-7. 2002..The difference suggests that the single-band model applies to the uncertainty effects in the temporal forced-choice task, whereas the multiple-band model does so in the spatial forced-choice task...
- Surround suppression in the human visual cortex: an analysis using magnetoencephalographyYoshio Ohtani
Faculty of Engineering and Design, Kyoto Institute of Technology, Matsugasaki, Sakyo ku, 606 8585, Kyoto, Japan
Vision Res 42:1825-35. 2002..We suggest that the surround suppression of the initial peak amplitude of the magnetic response may be ascribed to the inhibition of the neural activity at the early processing stage(s), presumably at V1, in the human visual cortex...
- Temporal summation of magnetic response to chromatic stimulus in the human visual cortexYoshio Ohtani
Faculty of Engineering and Design, Kyoto Institute of Technology, Matsugasaki, Sakyo ku, Kyoto 606 8585, Japan
Neuroreport 13:1641-4. 2002..The critical ED and SOA estimated from the peak amplitude vs. ED/SOA functions were about 50 ms. These values indicate the upper limit of temporal summation for chromatic stimuli in the human early visual cortex...
