Abstract

Severe behavioural deficits in psychiatric diseases such as autism and schizophrenia have been hypothesized to arise from elevations in the cellular balance of excitation and inhibition (E/I balance) within neural microcircuitry. This hypothesis could unify diverse streams of pathophysiological and genetic evidence, but has not been susceptible to direct testing. Here we design and use several novel optogenetic tools to causally investigate the cellular E/I balance hypothesis in freely moving mammals, and explore the associated circuit physiology. Elevation, but not reduction, of cellular E/I balance within the mouse medial prefrontal cortex was found to elicit a profound impairment in cellular information processing, associated with specific behavioural impairments and increased high-frequency power in the 30-80 Hz range, which have both been observed in clinical conditions in humans. Consistent with the E/I balance hypothesis, compensatory elevation of inhibitory cell excitability partially rescued social deficits caused by E/I balance elevation. These results provide support for the elevated cellular E/I balance hypothesis of severe neuropsychiatric disease-related symptoms.

  • Conventionally used AAV backbones with a 1.3 kb CaMKIIα promoter, WPRE, and human growth hormone polyadenylation signal have a capacity of 2.4 kb.

    “Conventionally used AAV backbones which include a commonly used neuronal expression cassette composed of 1.3 kb CaMKIIα promoter (which shows comparable expression efficiency with 0.4 kb CaMKIIα promoter [10] used in CWB), WPRE, and human growth hormone polyadenylation signal [23-25] has a capacity of 2.4 kb.”

    From Optimization of AAV expression cassettes to improve packaging capacity and transgene expression in neurons (2014) · cites this paper as [24]

    The Consequences of altered E/I balance section describes an AAV expressing SSFO–EYFP under a CaMKIIα promoter, supporting the use of that promoter in an AAV construct. The passages do not specify a 1.3 kb promoter, WPRE, a human growth hormone polyadenylation signal, or a 2.4 kb capacity; searches for those terms found no supporting passage. Page numbers were unavailable in our copy. (LLM, conf=0.83)

  • Alterations in the balance between excitatory and inhibitory signalling in neural micro-circuitry have been implicated in social deficits as seen in ASD and SCZ.

    “Importantly, alterations in the balance between excitatory and inhibitory signalling in neural micro-circuitry have been implicated in social deficits as seen in ASD and SCZ (Yizhar et al. 2011).”
  • Changes in PFC network activity directly affect cognitive and social skills.

    “Changes in PFC network activity directly affect cognitive and social skills”
  • Elevated levels of the repressive H3K27me3 mark, catalyzed by EZH2, have been observed in chronic stress models.

    “Elevated levels of the repressive H3K27me3 mark, catalyzed by the histone methyltransferase EZH2, have also been observed in chronic stress models.”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Yizhar et al., 2011

    The Consequences of altered E/I balance and Discussion passages concern optogenetic changes in cortical excitation and inhibition, not histone marks or chronic stress models. Searches for H3K27me3, EZH2, and stress-related epigenetic modification found no passage addressing the claim. Page numbers were not available in our copy. (LLM, conf=0.78)

  • These increases are associated with reduced expression of neuroplasticity-related genes, including CREB and enzymes involved in GABA synthesis.

    “These increases are associated with reduced expression of neuroplasticity-related genes, including CREB and enzymes involved in GABA synthesis (Yizhar et al., 2011).”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Yizhar et al., 2011

    The Discussion describes elevated excitation/inhibition balance and increased gamma power, but does not link either increase to reduced gene expression. Searches for CREB, neuroplasticity-related genes, and GABA-synthesis enzymes found no passage reporting the claimed association; the References list GABA-related gene-expression studies but do not establish it here.

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.
