A quantitative study of the human cerebellum with unbiased stereological techniques

Andersen, Birgitte Bo, Korbo, Lise, Pakkenberg, Bente·1992·Journal of Comparative Neurology

Abstract

Estimates of total number of different neuron and glial cell types in the dentate nuclei and the four major regions of the human cerebellum were obtained by new stereological methods. With the optical disector and Cavalieri methods, the total number of neurons and glial cells in the human cerebellum of five elderly men was estimated to be 105,000 x 10(6) (coefficient of variation, CV = 0.13). Of this total, the granule cells comprised 101,000 x 10(6) (CV = 0.13) and the Purkinje cells comprised 30.5 x 10(6) (CV = 0.13) of the neurons. The mean of the total number of neurons in the dentate nucleus was 5.01 x 10(6) (CV = 0.28). The average surface area of the human cerebellum was estimated to be 1160 cm2 (CV = 0.29). The rationale for the different sampling schemes used to quantify the various cell types is described.

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

  • Using more recent estimates of 21-26 billion cortical neurons and 101 billion cerebellar neurons, the total number of human brain neurons would exceed 120 billion.

    “With more recent estimates of 21–26 billion neurons in the cerebral cortex (Pelvig et al., 2008) and 101 billion neurons in the cerebellum (Andersen et al., 1992), however, the total number of neurons in the human brain would increase to over 120 billion neurons.”

  • Because cerebellar glial cells are outnumbered by neurons at least 25:1, the ubiquitous claim of 10 times more glial than neuronal cells in the whole human brain would require nearly one trillion glial cells in the remaining structures, which is unlikely since those structures are <10% of brain mass.

    “the only possible explanation for the ubiquitous quote of 10 times more glial than neuronal cells in the entire human brain would be the presence of nearly one trillion glial cells in the remaining structures alone – an unlikely scenario, since these structures represent <10% of total brain mass.”

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.
