WebJun 24, 2024 · Participants viewed a visual stream of black squares (temporal cue), followed by a white square (warning signal [WS]), and then a luminance-defined Gabor grating (target). Participants made a delayed, non-speeded judgment of the orientation of the grating, with the response elicited only after a variable time interval.

WebMay 29, 2024 · Gabor patterns are the product of a Gaussian envelope and a sinusoid function. In the wave grating formed by a sinusoid function, the image’s light intensity alternates between its darkest and brightest according to this function. If no envelope is applied, there would be sharp edges where the grating and the background meet. WebFor test stimuli we used matrix of Gabor grating. We used two types of 10 x 10 matrices with chaotic and ordered orientation of Gabor gratings. The size, brightness and contrast of the stimuli were identical. The chaotic and ordered patterns activated different brain areas. hines oil

WebOct 1, 1997 · Stereoacuity was determined for gratings and gabor patches as their orientation was varied. Acuity was constant for 1 c/deg and 2 c/deg gratings over the range 0–80 deg when it was expressed as positional shift at right angles to the grating orientation. The same was true of an 8 c/deg elongated gabor patch. However, the threshold …
