Brains are built, not born.
The brain starts to develop before birth
and carries on into early adulthood.
Scientists now believe that parts of the
brain are not fully developed until a
person is 25 years old.
Early childhood is an important
time for brain development.
During this time, more than a
million neural connections are
created every second!
