A progressive narrowing of the field of vision (tunnel vision) follows, as well as a decrease in the ability to see details (visual acuity). (medlineplus.gov)
Visual acuity is good in the previtelliform stage. (medscape.com)

In a human fMRI study, we measured the blood oxygen level-dependent activation (BOLD) responses of the primary visual cortex (V1) to the contours of large-diameter stimuli and found that activation closely matched the perceptual rather than the retinal stimulus size: the activated area of V1 increased or decreased, depending on the size of the preceding stimulus. (jneurosci.org)
In particular, the invariance of complex cell responses in primary visual cortex against small translations is commonly interpreted as a signature of an invariant coding strategy possibly originating from an unsupervised learning principle. (zotero.org)

Here, we show that the perceived size of a stimulus is significantly affected by the context of the scene: brief previous presentation of larger or smaller adapting stimuli at the same region of space changes the perceived size of a test stimulus, with larger adapting stimuli causing the test to appear smaller than veridical and vice versa. (jneurosci.org)
We presented stimuli to the left or right of fixation at encoding, followed by an episodic memory test with centrally presented retrieval cues. (neurosciencenews.com)

Here, using functional magnetic resonance imaging, we combine detailed mapping of both population receptive fields (pRF) and category-selectivity, with independently acquired resting-state functional connectivity analyses, to examine scene and retinotopic processing within medial parietal cortex. (frontiersin.org)
Functional connectivity with OPA was much weaker than with PPA, and similar to that with face-selective occipital face area (OFA), suggesting a closer link with ventral than lateral cortex. (frontiersin.org)
Consistent with prior research, we also observed differential functional connectivity in medial parietal cortex for anterior over posterior PPA, as well as a region on the lateral surface, the caudal inferior parietal lobule (cIPL). (frontiersin.org)

The question of how spatially organized activity in the visual cortex behaves during eyes-closed , lysergic acid diethylamide ( LSD )-induced "psychedelic imagery" (e.g., visions of geometric patterns and more complex phenomena) has never been empirically addressed, although it has been proposed that under psychedelics, with eyes-closed , the brain may function "as if" there is visual input when there is none. (beckleyfoundation.org)
To test this, it was hypothesized that, under LSD , patches of the visual cortex with congruent retinotopic representations would show greater RSFC than incongruent patches. (beckleyfoundation.org)
Consistent with our prior hypothesis, the difference between RSFC of patches with congruent retinotopic specificity (horizontal-horizontal and vertical-vertical) and those with incongruent specificity (horizontal-vertical and vertical-horizontal) increased significantly under LSD relative to placebo, suggesting that activity within the visual cortex becomes more dependent on its intrinsic retinotopic organization in the drug condition. (beckleyfoundation.org)

Although larger response magnitudes were reported for scenes presented contralaterally, fMRI adaptation was found not to depend on visual field position, indicating perhaps, the presence of receptive fields that span the vertical meridian ( MacEvoy and Epstein, 2007 ) and suggesting RSC plays a more prominent role in spatial memory rather than scene perception per se ( MacEvoy and Epstein, 2007 ). (frontiersin.org)
