Inhibitory neurons in human cortical circuits: substrate for cognitive dysfunction in schizophrenia

Open access
Lewis, David A·2014·Current Opinion in Neurobiology

Abstract

Schizophrenia is a disorder of cognitive neurodevelopment. At least some of the core cognitive deficits of the illness appear to be the product of impaired gamma frequency oscillations which depend, in part, on the inhibitory actions of a subpopulation of cortical GABA neurons that express the calcium binding protein parvalbumin (PV). Recent studies have revealed new facets of the development of PV neurons in primate neocortex and of the nature of their molecular alterations in individuals with schizophrenia. Other recent studies in model systems provide insight into how these alterations may arise in the course of cortical circuitry development.

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

  • Interneurons have been implicated in schizophrenia, anxiety disorders, and autism.

    “INs have also been implicated in other diseases including schizophrenia, anxiety disorders and autism”

    From GABAergic Interneurons in the Neocortex: From Cellular Properties to Circuits (2016) · cites this paper as Lewis, 2014

    The section “Alterations in cortical PV neurons in schizophrenia” links changes in inhibitory neurons to schizophrenia. The passages from our copy do not address anxiety disorders or autism, so the citation supports only one of the three conditions named. (LLM, conf=0.88)

  • The modification of the E/I balance within the PV-circuitry in PV-/- mice is reminiscent of the situation in schizophrenia, where NMDA receptor hypofunction leads to the reduction of GAD67 levels and thus GABA synthesis.

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.
