Primes

• Topographic Map
  • In neuroscience — the canonical case — retinotopy maps neighbouring retinal points to neighbouring V1 columns with the fovea massively over-allocated; tonotopy maps cochlear frequencies to A1; somatotopy maps the body surface onto the cortical strip with lips and fingertips hugely over-represented in the homunculus.

    This sourceOriginal mapping of the cortical sensory and motor homunculus with non-uniform magnification of hands, lips, and face.

Domain-specific

• Somatotopy
  • Wilder Penfield, operating on awake epilepsy patients at the Montreal Neurological Institute in the 1930s–40s, electrically stimulated successive points along the post-central gyrus and recorded the body part each patient reported feeling

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 2 citations: 1 supported. 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.
