DESCRIPTION
The brain consists of approximately 80% water, 10% fat, 8% proteins, and small amounts of carbohydrates, salt, and other minerals. Each one of its nerves functions by receiving electrochemical signals. Neural networks store memories by weakening or strengthening their many connections, and the result is memory. Encountering unfamiliar situations or looking at a portrait for the first time, for example, causes the cells to make new arrangements among themselves. The relevant nerves immediately strengthen their connections and attempt to define the situation. The data recorded enable the process to be carried out faster when the same situation is repeated, for what was new before will now appear familiar. The brain stores processes repeated throughout one’s life as a general image. Every recorded moment comes about by means of the 1,000 to 500,000 connections that the brain’s 100 billion nerves establish at a speed of 400 km per hour (248.5 mph).

The brain consists of approximately 80% water, 10% fat, 8% proteins, and small amounts of carbohydrates, salt, and other minerals. Each one of its nerves functions by receiving electro-chemical signals. Neural networks store memories by weakening or strengthening their many connections, and the result is memory. Encountering unfamiliar situations or looking at a por-trait for the first time, for example, causes the cells to make new arrangements among them-selves. The relevant nerves immediately strengthen their connections and attempt to define the situation. The data recorded enable the process to be carried out faster when the same situa-tion is repeated, for what was new before will now appear familiar. The brain stores processes repeated throughout one’s life as a general image. Every recorded moment comes about by means of the 1,000 to 500,000 connections that the brain’s 100 billion nerves establish at a speed of 400 km per hour (248.5 mph).With this superb capacity, the brain uses enough energy to run a dim lamp. Although it consti-tutes only one-fiftieth of the body’s weight, it consumes one-fifth of the body’s entire oxygen and glucose supplies. So important is the brain that it receives the first blood emerging from the heart; if only a small amount of blood is left, it still seeks to keep the brain alive. The heart, blood vessels, and all other organs are literally aware of this fact.The slightest brain damage can leave a person handicapped or even dead. In fact, this organ is so delicate that the failure of electrical signals to reach a single cell can cause the loss of one of the senses that enable us to perceive the outside world. No single point in it can come into being by chance, and its perfect organization and equipment cannot be altered in a ran-dom manner.This perfection, a very great blessing, reflects the creative artistry of Allah, Who treats His ser-vants well, the Beneficent Who creates to perfection, The Maker and He Who Reveals His Greatness in All: It is He Who shows you His Signs and sends down provision to you out of heaven. But none pay heed save those who repent. (40: 13) www.harunyahya.com
In Other Words, Creation. In Order to Create, Allah Has No Need to Plan
