The dentate gyrus: fundamental neuroanatomical organization (dentate gyrus for dummies)

Open access

Abstract

The dentate gyrus is a simple cortical region that is an integral portion of the larger functional brain system called the hippocampal formation. In this review, the fundamental neuroanatomical organization of the dentate gyrus is described, including principal cell types and their connectivity, and a summary of the major extrinsic inputs of the dentate gyrus is provided. Together, this information provides essential information that can serve as an introduction to the dentate gyrus--a "dentate gyrus for dummies."

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

  • For some time after action potential capability emerges, new granule cells exhibit excitatory instead of inhibitory responses to typically inhibitory neurotransmitter GABA, suggesting they are more likely to fire than mature granule cells.

    “For some time thereafter, new granule cells exhibit excitatory instead of inhibitory responses to typically inhibitory neurotransmitter GABA (Chancey et al., 2013), suggesting that these cells are more likely to fire than mature granule cells, which are strongly inhibited (Amaral et al., 2007; Pelkey et al., 2017).”

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.
