Human brain, the most
powerful and complex organ,
has been a great challenge
to scientists for centuries. Much research work has been done on it
from the ancient times to the present and people’s knowledge about
it develops step by step. Yet, no one knows exactly how it works as
the centre of mental activity, because the more scientists find out,
the more questions they are unable to answer. In the end, the author
is confident that with more advanced
equipment and techniques a true picture is expected to be revealed
in the coming future.. |
