- This is not incidental distortion but load-bearing content: the magnification budget encodes a tactile-acuity priority, and it predicts behaviour quantitatively (two-point thresholds scale inversely with cortical magnification).
This sourceShows perceptual acuity scales with cortical magnification, evidencing magnification as load-bearing content.

Duncan and Boynton show visual acuity thresholds scale roughly inversely with V1 cortical magnification, but in vision, not touch or two-point discrimination.
“means that acuity thresholds are roughly ... inversely proportional toM across eccentricity”

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.
