Neuronal Mechanism for Critical Period Unit (Yoko Yazaki-Sugiyama)

As we know from our own experience children can learn a new language and new sorts much easier and faster than adults. In the developmental time window, called ‘critical period’ the brain circuit can be intensively shaped or modified depending on their sensory experiences. However, this time window is limited, and we will never be again once this window close. If we could keep open this window longer or re-open it we would never have a trouble for learning 2^nd language in adult, easily get rehabilitated physically after injury etc. We are interested in this developmental time window ‘critical period;

• What is happening in the kids’ brain during they are receptive to accruing new information?   
• Why this time window is closed, possible to extend or re-open ?

We are curious to know what is happening to our brain when we are exploring our own environment in juvenile period…..
