Oscillations and Neuronal Dynamics in Schizophrenia: The Search for Basic Symptoms and Translational Opportunities

Uhlhaas, Peter J., Singer, Wolf·2015·Biological Psychiatry

Abstract

A considerable body of work over the last 10 years combining noninvasive electrophysiology (electroencephalography/magnetoencephalography) in patient populations with preclinical research has contributed to the conceptualization of schizophrenia as a disorder associated with aberrant neural dynamics and disturbances in excitation/inhibition balance. This complements previous research that has largely focused on the identification of abnormalities in circumscribed brain regions and on disturbances of dopaminergic mechanisms as a cause of positive symptoms and executive deficits. In the current review, we provide an update on studies focusing on aberrant neural dynamics. First, we discuss the role of rhythmic activity in neural dynamics and in the coordination of distributed neuronal activity into organized neural states. This is followed by an overview on the current evidence for impaired neural oscillations and synchrony in schizophrenia and associated abnormalities in gamma-aminobutyric acidergic and glutamatergic neurotransmission. Finally, we discuss the distinction between fundamental symptoms, which are reflected in cognitive deficits, and psychotic, accessory symptoms, the latter likely constituting a compensatory response for aberrant neuronal dynamics.

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.
