Single neural code for blur in subjects with different interocular optical blur orientation published in Journal of Vision
We studied the ability of the visual system to compensate for differences in blur orientation. Subjects selected the better image from pairs of images blurred with similar blur magnitude but different blur orientation, to generate positive and negative neural PSFs. We found that in subjects with similar and with different ocular PSF orientations between eyes, the orientation of the neural positive PSF was closer to the orientation of the ocular PSF of the eye with the better optical quality (average difference was ∼10°), while the orientation of the positive and negative neural PSFs tended to be orthogonal. These results suggest a single internal code for blur with orientation driven by the orientation of the optical blur of the eye with better optical quality.
