The Human Mystery
Devenye Friedenberg
 

The human brain is the most complex organ in the body. What scientists know about the brain is nothing compared to what they don’t.

One hundred million bits of information pour into your brain every second. In the brain stem there is a network of nerves the size of your pinky. This network is called the reticular formation. It acts as a “traffic control center,” monitoring the millions of messages coming into the brain each second.

Three weeks after conception, brain cells start forming. They grow in spurts, at times up to 250,000 cells per minute! At birth the brain weighs 14 ounces. During the first year it triples its size! In time about 100 billion neurons- (nerve cells), are packed into the brain, although it makes up only 2 percent of the body’s weight. Brain neurons do not actually touch each other. They are separated by synapses- the gap between a sending and a receiving neuron.

This is the little information about the brain that humans have learned.
