HOW DOES THE BRAIN FUNCTION
The cell on the left
with the fringe-like extensions is a nerve cell (neuron).
Billions of nerve cells, interconnected through these
branches extending out from the cell body, form a
network right through the body. There are gaps between
nerve ends, and nerve signals are carried across these
gaps to other nerve cells.
Scatter puzzle pieces irregularly
on the floor and suppose they are the entire knowledge about
the world. For instance, let some pieces represent light,
some represent colours and yet others represent sounds.
Now take these pieces one by one and start reassembling
them to form the picture. What you can do by thinking it
over at length is done hundreds of times in a second by
your brain, which works by Allah's inspiration. Do you wonder
The brain gathers the information
received from the eyes, nose, ears, skin, mouth etc. and
construes them. What makes this interpretation is a collection
of 100 billion nerve cells in your brain. These cells operate
unceasingly and enable you to see the colour of the apple
you eat, to recognise the voice of your best friend and
to perceive the smell of hot chocolate.
The picture on the next page
shows some children who are talking, hearing, smelling,
moving and sleeping in the brain. Of course this is an imaginary
picture, intended to show the particular portions of the
brain and their functions. In reality, what the brain consists
of is nerve cells, which can be seen only under a microscope.
Do you think nerve cells can see your favourite toy or taste
the flavour of chocolate ice cream? Certainly not. That
is because nerve cells are composed of fine pieces of flesh.
Hence there must be another being with supreme power who
created this wonderful world. This being is Allah. Allah,
the possessor of everything, creates everything perfectly
and presents each of us with a beautiful life. What we should
do in return is to be thankful to our Lord. Allah has given
our eyes and ears as an example, and has told us to give
thanks for them to Him:
It is He Who has created
hearing, sight and hearts for you. What little thanks you
show! (Surat al-Muminun: 78)
