    Experience-dependent cortical plasticity is heightened during developmental critical periods but declines into adulthood, posing a major challenge to recovery of function following injury or disease later in life. Our research aims to identify the mechanisms of experience-dependent cortical plasticity. Using visual system, a premier model of critical period, we take an integrated approach, combining molecular, anatomical, imaging, electrophysiological methodologies (e.g. in vivo viral gene transfer, optogenetics, chemogenetics, and two-photon time lapse imaging) (Science 2010, J Neurosci 2015, J Neurosci 2016, eNeuro 2017, Scientific Reports 2018, J Neurosci 2020). Our study would have direct implications for Amblyopia, a condition with limited adult-applicable treatment affecting 2–5% of the human population, but also for brain injury repair, sensory recovery, and the treatment of neurodevelopmental disorders.
