Abstract

Cortical gamma oscillations (20-80 Hz) predict increases in focused attention, and failure in gamma regulation is a hallmark of neurological and psychiatric disease. Current theory predicts that gamma oscillations are generated by synchronous activity of fast-spiking inhibitory interneurons, with the resulting rhythmic inhibition producing neural ensemble synchrony by generating a narrow window for effective excitation. We causally tested these hypotheses in barrel cortex in vivo by targeting optogenetic manipulation selectively to fast-spiking interneurons. Here we show that light-driven activation of fast-spiking interneurons at varied frequencies (8-200 Hz) selectively amplifies gamma oscillations. In contrast, pyramidal neuron activation amplifies only lower frequency oscillations, a cell-type-specific double dissociation. We found that the timing of a sensory input relative to a gamma cycle determined the amplitude and precision of evoked responses. Our data directly support the fast-spiking-gamma hypothesis and provide the first causal evidence that distinct network activity states can be induced in vivo by cell-type-specific activation.

  • PV-expressing basket cells have critical roles in generating and maintaining gamma, theta and ripple oscillations.

    “strong evidence supporting the view that PV-expressing basket cells have critical roles in the generation and maintenance of gamma, theta and ripple oscillations”

    From GABAergic Interneurons in the Neocortex: From Cellular Properties to Circuits (2016) · cites this paper as Cardin et al., 2009

    The sections “FS activation generates gamma oscillations” and “Natural gamma oscillations require FS activity” support a role for PV-positive fast-spiking interneurons in cortical gamma rhythms. The paper does not establish this claim for basket cells specifically or for ripple oscillations; it reports that stimulating these cells at 8 Hz did not increase 8-Hz power, rather than showing theta generation. It also does not establish maintenance of all three rhythms. Page numbers are unavailable in our copy. (LLM, conf=0.90)

  • Gamma activity has a close link to neuronal spiking, which IIT considers a constituent property of the physical substrate of consciousness.

    “Gamma activity was analysed because of its close link to neuronal spiking47, which IIT considers a constituent property of the physical substrate of consciousness5.”
  • Cortical PV cells contribute to synchronous oscillatory activity, particularly in the gamma range.

    “Cortical PV cells contribute to synchronous oscillatory activity (Cardin et al., 2009; Sohal et al., 2009; Uhlhaas et al., 2009), particularly in the gamma range (∼30–100 Hz).”
  • FS-PV interneurons are at the origin of gamma oscillation in the cortex and contribute to cognitive functions.

  • Optogenetically driving inhibitory interneurons specifically enhances slow gamma frequency oscillations throughout cortex, reducing circuit noise while amplifying circuit signal.

    “Two foundational optogenetic studies demonstrated that optogenetically driving inhibitory interneurons specifically enhances slow gamma frequency oscillations throughout cortex, reducing circuit noise while amplifying circuit signal [201, 202].”

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.
