Abstract

In six control subjects pars compacta nerve cells in the ventrolateral substantia nigra had a lower melanin content than nerve cells in the dorsomedial region. This coincides with a natural anatomical division into ventral and dorsal tiers, which represent functionally distinct populations. In six cases of Parkinson's disease (PD) the ventral tier showed very few surviving nerve cells compared with preservation of cells in the dorsal tier. In 13 subjects without PD, but with nigral Lewy bodies and cell loss, the degenerative process started in the ventral tier, and spread to the dorsal tier. This pattern of selective degeneration of nigrostriatal neurons is not seen in ageing or after acute administration of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
