These consisted of three circular Gabor patches within which the sinusoidal ... chosen because they are ideally suited to analysis by orientation- and frequency-selective mechanisms early in ...

The target consisting either of a Gabor patch or a tone was presented for 25 ms, Participants had to differentiate between 3 different Gabor rotations or tone pitches, ... while the subsequent block ...

PurposeAstigmatism can lead to meridional amblyopia, an orientation-specific visual deficit. ... The initial contrast of the Gabor patches was set at 20% for spatial frequencies of 0.6, 1.3, and 3.0 ...

Each stimulus condition was presented for 1 s and repeated 5 or 10 times. A blank screen with equal luminance to the Gabor patch was presented for 0.25 s during the stimulus interval. Stimuli were ...

Experiment 1: counting features. We asked observers to count highly visible, resolvable features (small Gaussian or Gabor patches) that varied in number ().The non-amblyopic eyes of amblyopes ...

Gratings drifted in 36 different directions between 0 to 360° in 10° steps in a pseudorandom order. The stimulus in each condition was presented for 1 s and repeated 5 or 10 times. A blank screen with ...

Introduction: Learning through perceptual training using the Gabor patch (GP) has attracted attention as a new vision restoration technique for myopia and age-related deterioration of visual acuity ...

Neuronal responses were measured using a high-contrast (0.9) Gabor patch, which is a Gaussian-windowed sinusoidal grating, drifting at 2 cycles/sec in opposite directions perpendicular to the Gabor’s ...
