“25 sparseness of representations in different parts of the human hippocampal system or between the hippocampus and neocortex [1], but in macaques it has been shown that representations in the hippocampus are more sparse than in three neocortical areas [6], in line with the pattern separation hypothesis [3,4].”

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.
