Alterations in Cortical Network Oscillations and Parvalbumin Neurons in Schizophrenia

Abstract

Cognitive deficits are a core clinical feature of schizophrenia but respond poorly to available medications. Thus, understanding the neural basis of these deficits is crucial for the development of new therapeutic interventions. The types of cognitive processes affected in schizophrenia are thought to depend on the precisely timed transmission of information in cortical regions via synchronous oscillations at gamma band frequency. Here, we review 1) data from clinical studies suggesting that induction of frontal cortex gamma oscillations during tasks that engage cognitive or complex perceptual functions is attenuated in schizophrenia; 2) findings from basic neuroscience studies highlighting the features of parvalbumin-positive interneurons that are critical for gamma oscillation production; and 3) results from recent postmortem human brain studies providing additional molecular bases for parvalbumin-positive interneuron alterations in prefrontal cortical circuitry in schizophrenia.

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

  • Parvalbumin- and perineuronal-net-mediated alterations are likely to contribute to dysfunction of the layer 3 parvalbumin-pyramidal cell local circuitry that generates gamma oscillations and thus to the neural basis for impairments in dorsolateral prefrontal cortex gamma oscillations seen during cognitive tasks in individuals with schizophrenia.

    “Through a variety of mechanisms, PV and PNN-mediated alterations are likely to contribute to dysfunction of the layer 3 PV-PC local circuitry that generates γ-oscillations (Gonzalez-Burgos et al, 2015) and thus to the neural basis for the impairments in DLPFC γ-oscillations seen during cognitive tasks in individuals with schizophrenia (Uhlhaas and Singer, 2015).”

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.
