>The optimization process that trained the human brain is called evolution
A human brain that doesn't get visual stimulus at the critical age between 0 and 3 years old will never be able to tell the difference between a cat and a dog because it will be forevermore blind.
I heard a similar case before I did my A-levels, so at least 22 years ago, where the person had cateracts removed and it took a while to learn to see, something about having to touch a statue (of a monkey?) before being able to recognise monkeys?
