Abstract

Neural circuits are shaped by experience in early postnatal life. Distinct GABAergic connections within visual cortex determine the timing of the critical period for rewiring ocular dominance to establish visual acuity. We find that maturation of the parvalbumin (PV)-cell network that controls plasticity onset is regulated by a selective re-expression of the embryonic Otx2 homeoprotein. Visual experience promoted the accumulation of non-cell-autonomous Otx2 in PV-cells, and cortical infusion of exogenous Otx2 accelerated both PV-cell development and critical period timing. Conversely, conditional removal of Otx2 from non-PV cells or from the visual pathway abolished plasticity. Thus, the experience-dependent transfer of a homeoprotein may establish the physiological milieu for postnatal plasticity of a neural circuit.

  • Experience-dependent accumulation of exogenous OTX2 is necessary for the formation of PNNs and critical period closure in the visual cortex.

    “On the other hand, an experience-dependent accumulation of exogenous OTX2, a homeoprotein commonly bound to PNNs and PV1 cells in the mPFC (Lee et al., 2017), is necessary for the formation of PNNs and critical period closure in the visual cortex (Sugiyama et al., 2008).”
  • Reductions of inhibitory neural activity in adulthood have increased visual plasticity in rodents and even restored visual function in amblyopic adult rats.

    “For example, reductions of inhibitory neural activity in adulthood have increased visual plasticity in rodents (He et al., 2007, Sugiyama et al., 2008, Harauzov et al., 2010) and even restored visual function in amblyopic adult rats (Vetencourt et al., 2008).”

    From The impact of developmental timing for stress and recovery (2015) · cites this paper as Sugiyama et al., 2008

  • Disruption of excitatory-inhibitory balance shifts the timing and quality of critical period development in primary visual cortex.

    “Accordingly, disruption of E-I balance powerfully shifts the timing and quality of critical period development, as seen in the primary visual cortex (V1) (27–29).”
  • PNN disruption prevents persistent uptake of Otx2 homeoprotein into enwrapped PV cells required for their maintenance.

    “Second, PNN disruption prevents the persistent uptake of Otx2 homeoprotein into the enwrapped PV-cells required for their maintenance (27, 40, 41) (Fig. S3).”
  • Compromised PNNs prevent persistent uptake of Otx2 homeoprotein into enwrapped PV cells needed for their maturation, including PNN maintenance.

    “Compromised PNNs prevent the persistent uptake of Otx2 homeoprotein into the enwrapped PV-cells needed for their maturation (including PNN maintenance itself) (27, 40, 41).”

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.
