Everything that you do, think, say, or feel takes place inside the brain. Nerves belonging to the brain, known as neurons, make such communication possible. An average neuron is 10 microns in size, and a micron is equivalent to .001 millimeter. They are so small that 50 average-sized ones could fit into the period at the end of this sentence. The brain contains an average of 100 billion neurons. It would take us 3,171 years to count all of them; if we laid them out end to end, they would stretch for 1,000 kms (621.4 miles). The presence of such an extensive communication network in an organ that represents only 2% of a human being’s body weight is certainly a wondrous miracle.1
Even if we were to bring together all man-made communication networks in the world, we could never obtain such a systematic, complex, flawless, and rapid system. This system must function in an incredible state of activity to produce even the smallest movement that we wish to make. Each person was given this flawless communication system while in the womb. No technology in the world can compare with the sublime, complex co-ordination displayed in the human brain.
If even a small component of this perfect system is damaged or if a single neuron fails to function properly, the brain’s electrical transmission may be damaged, which leads to losses of feeling and sensation. In that event, any random event that occurs in this extraordinarily delicate system could do away with the majority, or even all, of its cerebral functions. This extraordinary structure belongs to Allah, Lord of Majesty and Greatness, Who creates all the living cells and makes them a means by which life is bestowed:
Say: “Travel throughout the land and see how He brought Creation out of nothing. Then later Allah will bring about the next existence. Allah has power over all things.’ (Surat al-‘Ankabut, 20)
