How Does The Brain Functions?
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 how?
1-Taste 2-Speech 3-Motion 4-Touch 5-Smell 6-Sleep
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)
