Plasticity of the visual cortex and treatment of amblyopia. (2014, neutral): “Conversely, attaining a threshold level of intracortical inhibition precipitates closure of the critical period such that GAD65 knock-out mice whose GABAergic transmission has been enhanced early in life become insensitive to monocular deprivation as adults [6].”
Origins of Cortical Interneuron Subtypes (2004, background): “In addition, they appear to regulate neuronal proliferation and migration later in corticogenesis (Owens and Kriegstein, 2002), as well as the postnatal development of cortical circuitry (Huang et al., 1999; Fagiolini and Hensch, 2000; Zheng and Knudsen, 2001).”
Tumor necrosis factor-alpha mediates one component of competitive, experience-dependent plasticity in developing visual cortex. (2008, neutral): “Recent studies of other transgenic mice have highlighted the possibility that apparent defects in plasticity can arise from changes in the timing of the critical period ( Fagiolini and Hensch, 2000; Hanover et al., 1999; Huang et al., 1999).”
Development and plasticity of cortical areas and networks (2001, background): “Rearing animals in complete darkness delays both the end of the critical period and the maturation of GABA-mediated inhibitio”
Enriched Odor Exposure Increases the Number of Newborn Neurons in the Adult Olfactory Bulb and Improves Odor Memory (2002, background): “…recent analyses of this plasticity indicate that a developmental mismatch between inhibition and excitation could provide a time frame during which the reorganization of cortical circuitry can be particularly influenced by sensory experience (Huang et al., 1999; Fagiolini and Hensch, 2000).”
Trajectories of brain development: point of vulnerability or window of opportunity? (2003, background): “D - aspartate ( NMDA ) receptor sys - tem [ 65 ] , the neurotrophin BDNF [ 89 ] , GABA [ 61 ] , class I major histocompatability ( I MHC ) genes [ 41 ] , and mod - ulatory neurotransmitter systems , especially serotonin [ 218 ] .”
Common circuit defect of excitatory-inhibitory balance in mouse models of autism (2009, neutral): “GABA-synthetic enzyme (GAD65 KO) in mice delays plasticity onset within the visual cortex indefinitely [7], which can be rescued at any age with benzodiazepines [8].”
Critical period regulation. (2004, background): “Animals reared in complete darkness from birth express a delayed onset profile with plasticity persisting into adulthood (Fagiolini et al. 1994, Iwai et al. 2003, Mower 1991).”
Neurodevelopment of the association cortices: Patterns, mechanisms, and implications for psychopathology (2021, neutral): “…period plasticity in sensory cortices, as increasing or decreasing inhibitory interneuron activity alone can accelerate or delay the timing of a critical period (Fagiolini and Hensch, 2000; Hensch, 2005; Larsen and Luna, 2018; Reh et al., 2020; Takesian and Hensch, 2013; Toyoizumi et al., 2013).”
Experience and Activity-Dependent Maturation of Perisomatic GABAergic Innervation in Primary Visual Cortex during a Postnatal Critical Period (2004, background): “…inhibition has been implicated in both the onset and the closure of the critical period of ocular dominance plasticity (Hanover et al., 1999; Huang et al., 1999; Fagiolini and Hensch, 2000; Kirkwood and Bear, 1994), but the specific class of GABAergic synapses and mechanisms involved are unclear.”
Connectionist Models in Developmental Cognitive Neuroscience : Critical Periods and the Paradox of Success (2005, background): “…the development of inhibitory circuitry can be controlled by genetic (Hensch et al., 1998; Huang et al., 1998; Fagiolini et al., 2004) and pharmacological (Fagiolini & Hensch, 2000) factors that can be decoupled from activity-dependent changes in plasticity evident during the critical period.”
