Abstract

1. The authors' goal was to compare the size and density of Purkinje cells in the cerebellum of subjects with and without autism. Blocks of cerebellum were dissected at autopsy from the brains of age, sex- and postmortem-intervaled (PMI) groups of autistic and normal control individuals (N = 5 per group). Frozen, unfixed blocks were sectioned and stained with 1% cresyl violet. 2. The linear, molecular, granular densities and cross-sectional area of Purkinje cells were measured using computer-assisted image analysis. The average cross-sectional areas of Purkinje cells of the patients with autism were smaller by 24% when compared to the normal subjects. Two of the five autistic subjects had mean Purkinje cell sizes that corresponded to greater than 50% reduction in size. There was a substantial effect size difference in Purkinje cell size (eta2 = 0.29) between control and autistic brains (F(1, 8) = 3.32, P = 0.106). No differences in Purkinje cell densities were observed between the two groups 3. These data indicate the possibility of Purkinje cell atrophy in autism with significant neurohistological heterogeneity among individuals diagnosed with this disorder.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reductions in the size and number of Purkinje cells in the cerebellar vermis in autism remain unresolved because of a lack of stereological reports.

    “Reductions in size and number of Purkinje cells in cerebellar vermis in autism remain unresolved due to lack of stereological reports [311];”
  • The mean size of Purkinje cells in subjects with ASD is significantly smaller than in controls.

    “The mean size of Purkinje cells in subjects with ASD is significantly smaller compared to controls [108, 380].”

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.
