Abstract

The maturation of inhibitory circuits in juvenile visual cortex triggers a critical period in the development of the visual system. Although several manipulations of inhibition can alter the timing of the critical period, none have demonstrated the creation of a new critical period in adulthood. We developed a transplantation method to reactivate critical period plasticity in the adult visual cortex. Transplanted embryonic inhibitory neurons from the medial ganglionic eminence reinstate ocular dominance plasticity in adult recipients. Transplanted inhibitory cells develop cell-type-appropriate molecular characteristics and visually evoked responses. In adult mice impaired by deprivation during the juvenile critical period, transplantation also recovers both visual cortical responses and performance on a behavioral test of visual acuity. Plasticity and recovery are induced when the critical period would have occurred in the donor animal. These results reveal that the focal reactivation of visual cortical plasticity using inhibitory cell transplantation creates a new critical period that restores visual perception after childhood deprivation.

  • The shift in inhibition is likely mediated by PV+ interneurons, which are also thought to regulate sensitive period plasticity in sensory cortex, making them attractive candidates for pubertal regulation of association cortex plasticity.

    “This shift in inhibition is likely mediated by PV+ interneurons, which are also thought to regulate sensitive period plasticity in sensory cortex (Davis et al., 2015; de Villers-Sidani et al., 2008; Hensch, 2005; Le Magueresse and Monyer, 2013; Werker and Hensch, 2015), and therefore are attractive candidates for pubertal regulation of association cortex plasticity.”
  • Increasing inhibition from PV+ interneurons is implicated in regulating sensitive period plasticity in primary sensory cortices.

    “Increasing inhibition from PV+ interneurons is implicated in regulating sensitive period plasticity in primary sensory cortices (Davis et al., 2015; Heimel et al., 2011; Hensch, 2005; Le Magueresse and Monyer, 2013; Werker and Hensch, 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.
