Abstract

A systematic classification and accepted nomenclature of neuron types is much needed but is currently lacking. This article describes a possible taxonomical solution for classifying GABAergic interneurons of the cerebral cortex based on a novel, web-based interactive system that allows experts to classify neurons with pre-determined criteria. Using Bayesian analysis and clustering algorithms on the resulting data, we investigated the suitability of several anatomical terms and neuron names for cortical GABAergic interneurons. Moreover, we show that supervised classification models could automatically categorize interneurons in agreement with experts' assignments. These results demonstrate a practical and objective approach to the naming, characterization and classification of neurons based on community consensus.

  • Chandelier interneurons are the most morphologically recognizable interneurons due to candlestick-like synaptic terminal arrays targeting the axon initial segment of pyramidal cells.

    “Chandelier INs, also known as axo-axonic neurons, are the most recognizable INs in terms of morphology (DeFelipe et al., 2013) due to the unique candlestick-like synaptic terminal arrays they form to specifically target the axon initial segment of pyramidal cells.”

    The Historical overview (page unavailable) says chandelier cells are readily distinguished by clear morphological attributes, but it does not rank them as the most recognizable interneurons. The Anatomical section (page unavailable) identifies chandelier cells as axo-axonic cells targeting the axon initial segment of pyramidal cells; the cited passages do not describe candlestick-like terminal arrays. (LLM, conf=0.82)

  • A systematic attempt to classify neocortical interneurons by morphology alone showed too many ambiguities for experts to agree on most subtype identities.

    “an attempt to produce a systematic classification of neocortical INs based on morphological features alone by a large number of investigators showed that there are too many ambiguities for “experts” to agree on the identity of most IN subtypes when strictly relying on morphological data”

  • The definition of a cell type in the brain remains controversial.

    “the definition of a cell type in the brain remains controversial20,21”
  • The field has not readily converged on a consensus number or definition of neuronal cell types.

    “the field has not readily converged on a consensus number, or even definition, of neuronal cell types”
  • In V1 L4 of adult mice, seven inhibitory types of neurons were identified using whole-cell recordings with morphological recovery.

    “Using whole-cell recordings with morphological recovery, we identified one major excitatory and seven inhibitory types of neurons in L4 of adult mouse visual cortex (V1).”

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.
