Primes¶
- Receptive Field
- And the prime's gap prediction is the blind spot — the optic-disc region has no photoreceptors, so a stimulus there falls outside every field's coverage and produces literal silence (a scotoma), a coverage failure in the tiling geometry, not a defect in any unit.
This sourceMaps the physiological blind spot — the optic-disc region with no photoreceptors — as a coverage gap (scotoma) in the retinal tiling whose representation appears in visual cortex, confirming the gap is in the tiling geometry, not a unit defect.

Confirms the blind spot is an optic-disc scotoma lacking photoreceptors, with cortical pRFs sparing it; the tiling-geometry framing is the article's own.
“In each eye we have a small region of blindness corresponding to the optic disc, because the retina contains no photoreceptors here.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
