Critical period in brain development is a window of time when increased neuroplasticity makes it easy for the brain to rewire its structures to optimally avail of the inputs from the sensory world. Depriving vision in one eye results in a shift in ocular dominance. Exposing a little child to sounds of its native language provides specialized processing capacity for the language's phonetic profile. Once the critical period is over, reversing the changes in cortical wiring is difficult or impossible.
