Silicon Model of Motion Adaptation in the Fly Visual System
We describe an adaptive version of the Hassenstein–Reichardt detector, which models direction-selective computation in the fly. The Hassenstein– Reichardt detector has a fixed time constant. However, several researchers have shown that the time constant of the fly’s motion system adapts to the temporal frequency or speed of the input. The time constant of our adaptive detector also adapts to th...
متن کاملMotion blur and motion sharpening in the human visual system
The effect of motion sharpening upon blur discrimination thresholds was examined for a range of speeds and blur widths. Blur discrimination thresholds were measured for drifting edges whose blur was either physically or perceptually constant. Under conditions where edges were kept at a constant physical blur width, discrimination thresholds rose as a function of speed as previously reported. Ho...
متن کاملA model of encoding and decoding in V1 and MT accounts for motion perception anisotropies in the human visual system.
We used the motion aftereffect (MAE) to psychophysically characterize tuning of motion perception in the human visual system. The function relating MAE strength and the range of directions present in the adapter stimulus provides information regarding the width of direction tuning of motion adaptation. We compared the directional anisotropy in MAE tuning width to the well-known oblique effect i...
متن کاملOrientation anisotropies in human visual cortex.
Representing the orientation of features in the visual image is a fundamental operation of the early cortical visual system. The nature of such representations can be informed by considering anisotropic distributions of response across the range of orientations. Here we used functional MRI to study modulations in the cortical activity elicited by observation of a sinusoidal grating that varied ...
متن کاملTitle: Orientation Anisotropies in Human Visual Cortex
Representing the orientation of features in the visual image is a fundamental operation of the early cortical visual system. The nature of such representations can be informed by considering anisotropic distributions of response across the range of orientations. Here, we used functional magnetic resonance imaging to investigate modulations in the cortical activity elicited by observation of a s...
